The Red Devils' utility man is part of the Three Lions' 23-man contingent for next month's tournament in Brazil, but Roy Hodgson's side are not expected to seriously challenge at the business end of the competition.
Hodgson has earned widespread plaudits for picking a youthful-looking side that includes the likes of Ross Barkley, Raheem Sterling and Luke Shaw.
The average age of the squad is just 26 compared to 29 from the 2010 squad that were eliminated by Germany in South Africa.
Unusually, expectations are low for the England squad, but Jones, who himself is 22, sees no reason why the team can't upset the odds in South America.
Speaking to Sky Sports News, the United star said: "We go there with great belief and confidence about ourselves, we know that if we can play at our best on our day, we can beat any team.
"There's no point getting on the plane if we don't believe we can go far, and who knows, maybe even win the tournament. We're all confident and looking forward to the tournament."
Jones was speaking during a fundraising event in London, and the former Blackburn Rovers youngster spoke of the "real buzz" the squad felt from their pre-World Cup get-together.
"This is the first time we’ve actually met up and the feeling in the car on the way down, you get a real buzz about it," he added. "It’s going to be a fantastic tournament and all the lads are excited about it."
Meanwhile Hodgson plans to take his team to train in Portugal on Monday in an attempt to acclimatise as best as possible for the heat and humidity that Brazil will provide.
