Coach Souleymane Camara said his side can reach the knockout round for the first time in their history.
"It's too early to talk about winning the competition. We have got players who are still developing. They're going to be coming up against professional players who've already picked up valuable experience at reserve-team level with clubs like Paris, Lyon and Marseille," he said.
"Despite the gap we'll be giving everything we have got to go as far as we can."
Camara said it won't be easy for his side to get past the group stage.
"It's a difficult group. The Iranians played Japan three times and came away with a win and two draws. I'm expecting them to be very strong. I've spoken with the coach of Costa Rica, who I think will be one of the best teams at the U-17 World Cup, along with Brazil.
Guinea were knocked out in the first round at Chile 2015 and qualified for India 2017 after finishing third at the U-17 Africa Cup of Nations.
The Ebola virus struck Guinea hard between 2014 and 2016, claiming the lives of 2,543 people and sending thousands to hospital. During that time the country's clubs and national team were forced to play their home games far away.
Looking back on the obstacles Guinea faced in their qualifying campaign, Camara said: "It's the result of a lot of hard work. We made it despite the problems we had at the Africa Cup of Nations. I'm a young coach coming up against some very experienced operators, but that has not stopped us from earning our place at the U-17 World Cup."
"Our preparations are going as expected. We had a one- month training camp in Italy followed by another 10-day camp in Abu Dhabi. And we're going to keep on preparing hard so that we can spring a surprise at the World Cup," he added.
