The 19-year-old defender is currently in South Korea as part of Paul Simpson's England Under-20 side, along with fellow Boro youngster Harry Chapman.
After featuring alongside Chapman in Wednesday's 2-1 win against Costa Rica, which secured England's passage to the tournament's quarter-finals, Fry says he wants the campaign to go on for as long as possible.
"This is a massive opportunity for the whole squad and for me personally to impress people back at Middlesbrough," he told The Sun.
"Obviously last season was a disappointment getting relegated, but this year I really want to show everyone that I deserve to be part of the first team squad and try and force my way into the team.
"And I can start by doing that out here in South Korea.
"At this level we are coming up against the best players in the world our age and lots of current stars like Cesc Fabregas and David Silva have played in this competition in the past.
"We could be playing against the next big star for the next decade now, so this experience is unbelievable for me and the lads."
Although England were largely in control against their Central American opponents in midweek, Everton's Ademola Lookman firing the Young Lions into a two-goal lead, Costa Rica did set up a nervy finish as Randall Leal tucked home the rebound after seeing his penalty saved by Freddie Woodman.
It's that kind of competitive environment which Fry says provides an invaluable learning curve for him and his teammates.
"Even at 2-0 up, what I've learnt is that no matter how comfortable you think you are, you have to remain concentrated at all times," he said.
"They got one back near the end which made it tough, but we held our nerve and battled on to get the win. We were delighted.
"I should have scored twice too - especially the last one where I just tried to glance it in. It's one of them where nine times out of ten I'd have put it away.
"I'm just glad that we held on and got the job done."
Fry had to work his way into contention for Simpson's Young Lions. Having had to settle for a place in the bench in England's first two group games, against Argentina and Guinea, the Boro youngster has played every minute of the last two matches - with Costa Rica's penalty rebound the solitary goal England have conceded in that time.
The centre-back hopes he has done enough to retain his place for Monday's last eight tie with Mexico.
"I had to wait for my chance but I'm pleased with the two performances. I've put in and hopefully that has put me firmly in the manager's mind for Mexico," he said.
"We've played them before and they are a very good team. But so are we and we'll be ready to give it everything and hopefully pass another test."
