The word "victory" is very similar to the word "win" when it’s used as a noun. Sporting events, wars, and other forms of competition usually result in some kind of victory for one side or the other:
Jose lead his team to victory this season.
Natalya loves the taste of victory.
The people of Libya celebrated their victory over the fall of a brutal dictator.
They couldn’t relax until the victory was certain.
Victory will be mine.
When this word is in the form of an adjective, it becomes "victorious."
It was a tough match, but in the end our team was victorious.
Once the battle concluded, the victorious army did not harm the people of the city.
The victorious team claimed the trophy.
A person who wins is a victor:
It was a tough fight, but it was obvious to all who the victor was.
To the victor go the spoils. (This is an expression. It means that the person or the group that wins a competition or a battle gets the material things that go along with a win.)
