The France coach says he is staying realistic about his side's chances in Brazil and claims players are becoming more isolated because of the use of personal technology.
Les Blues did not make it out of the group stage in South Africa in 2010 and endured a similarly torrid time at the European Championship in 2012, which was marred by in-fighting within the camp.
France was forced to come from behind to beat Ukraine in its playoff match to reach this summer's finals, and Deschamp is being realistic about its chances of success.
"I'm going to Brazil with lots of ambition but I'm a realist, too," the 45-year-old told reporters. "There are countries that are much better than us on paper. We can't hide from the truth. The only match that France won in the group stage of a World Cup in the last 12 years was against Togo in 2006.
"I can't talk about winning the World Cup. There are teams who are far ahead of us, including a team who won the last World Cup and the last two European Championships [Spain]. There are six or seven. To win it for us would be viewed as a miracle."
The former Olympique de Marseille and Juventus coach also criticized the way his players have become "isolated and selfish" due to the increased use of personal gadgets.
"Managing players is harder these days because of the arrival of new technology," said the 45-year-old. "They are all using it in their spare time so they become more isolated and selfish. They share less, they talk less. They have apps, their phones and the Internet but they are less used to talking to people.
"Nowadays you never see players playing cards. We used to sit around playing cards together all the time. But I can't fight that, I have to adapt and change. So I have to find new ways of getting people to interact, because it is still healthy to know whether the guy sitting next to you at dinner has a wife or kids or whatever."
The 1998 World Cup winner also explained France's decision to stage a warm up game against Norway on Tuesday in preparation for this summer's tournament.
"Why did we choose Norway? First, because we need teams that are available," said Deschamps. "Norway were free and available. It is with great pleasure that we welcome them to the Stade de France.
"In their style of play, they are a European team. They don't practice a Scandinavian style of football, I mean they don't play a straight football with long balls," he said. "They play on the ground, they're a technical team so it's good for us to be tested against them."
