What's the point of samba?

Samba is a Brazilian football and a part of Brazilian culture. They will dance when they enter the stadium after scoring the goal, after winning the game. Is this to despise their opponents from the beginning?

Secondly, the most important point, which is ignored by more fans, is that Brazilian players are not just celebrating, but responding to those who discriminate against them.

Dancing is for a goal, for the team, for the performance, and for the result.
