How are the words enter and victor different

Victor - a person who defeats an enemy or opponent in a battle, game, or other competition.
Enter - begin to be involved in. 
In this case (because of the 2 words), I think that the victor is the person who wins the competition while the word enter, or the phrase to enter, is probably meant as in to enter the competition. The question wasn't entirely clear but I hope I have sort of answered it. :)
