Win like you’ll see the other team again. You probably will.

Worlds are smaller than they feel at the time. The person you beat today turns up later as a colleague, a hiring manager, or somebody with a say in what you get next. How you handled the moment is what they will remember, long after the result stops mattering.

After the next thing that goes your way, keep the celebration between you and your own side. Say something genuine to whoever came second. It costs nothing now and saves you something later.
