However, there are a few crucial details to consider:
* He was underage: Harry was only 14 years old, while the minimum age for participation was 17.
* He didn't put his name in: Harry never intentionally entered the Tournament. He had no desire to participate.
* Someone else entered his name: Barty Crouch Jr., disguised as Alastor Moody, put Harry's name in the Goblet of Fire to ensure Harry's participation in the tournament. Crouch Jr. wanted Harry to die so Lord Voldemort could return.
Ultimately, even though the Goblet of Fire chose Harry, it was a result of a deliberate, manipulative act by Crouch Jr., not a genuine selection by the magical artifact.
