Billy's older brother and Gloucester teammate Freddie has been capped three times for the England senior side.
As well as his sibling's achievement being something he is proud of, it is something the 19-year-old uses as motivation for his own career.
"I am massively proud of what Fred's achieved and he has done real well," he said.
"To see him break into the senior set up and make his debut against New Zealand and win, it makes me realise just how much I want it.
"I can pick his brain, he helps me out. I am really keen to follow in his footsteps but to do it in my own way as well."
Burns junior paints the picture of a nurturing relationship, adding: "Fred teaches me a lot. We are at the same club at the moment and we are out training together. We help each other out. He will watch my games with me afterwards on the computer.
"We get on well to be fair but there is always that little competitive edge. We do a lot of our kicking practice together, we will put coffees and cakes on it and sometimes it can get a bit heated!"
A recent visit to the England Under-20s camp by Great Britain's Olympic medal winning triathletes and brothers Alistair and Jonathan Brownlee brought home that special bond shared between sporting siblings.
"It was quite interesting as they are brothers in the same sport, so I could really relate to that," added Burns.
"They came into speak to us. It was really refreshing how they help each other out; they want the best for each other and work in a team almost.
"The fact that they are so competitive with each other and want the best for each other, it was very similar to Fred and myself."
Burns is the place kicker for the England Under-20s side and gives an engaging insight into the psychology of that role.
"Kicking is a very high-pressure thing to do," he said. "It is nice when you get it right but when it doesn't go your way; you have got to pick yourself back up.
"It is what we practice day in, day out to do, and we want to be in the position where we have got those big kicks with the pressure. It is just how you handle it. I enjoy kicking under pressure.
When we went to France it was a pretty hostile environment. But kicking is one of those things I am passionate about and you live for those moments where the chips are down and you have to put a kick over."
When it comes to pre-match rituals, the fly-half is not particularly superstitious but the one check he does make comes back to family.
"I am always quite chilled before games to be honest. If I get too worked up, I get in a state and I get nervous," he said.
"But whenever my parents are watching, I always try to spot them in the crowd before the game starts, just to make sure that they are there and they are all right."
Representing England in the Under-20s Six Nations Championship is something that means a lot to Burns and his teammates, adding: "It is pretty special. Obviously, representing your country at any level is a special achievement and is something all the boys cherish.
"I am enjoying playing with a different group of boys. Getting outside of your clubs and playing with guys the same age, with some of the guys that have come through at the same time as you at schools and at clubs is a really good opportunity to show what we have got."
Another reason why Burns is keen to impress at Under-20s level is by means of a thank you to those who have fostered his talent at club level.
He said: "Gloucester has helped me massively. Representing England is sort of giving something back to them and it shows how the coaches have put me in the position I am in now, so I owe them a lot. Whenever, I play I want to do them proud, as well as my family and friends."
A particularly special moment came for both Burns brothers at Kingsholm in November, when they played together for the first time but it is something Billy would love to one day do at senior level for England.
"We did it for Gloucester at the beginning of the season and that was a massively special moment for myself, Freddie, our family and friends," he added.
"To do that for England would be a dream come true. It is a massive achievement to do it at club level but to go one better and do it internationally, I don't know what that would be like."
That is certainly a burning ambition to help drive a young player towards success.
