What kind of information is vivid and easy to modify in the lottery of football match?

First of all, what is the concept of "lottery competition"? I don't understand. Is there a contest in the lucky draw? Or the lottery part of the game?

What kind of information expression is too general. Do you want comments, diagrams or computer program simulations?

If you want to express the lottery results, it may be better to express them by grouping and binary tree.

The points table is used in the group stage and the binary tree promotion road map is used in the knockout stage.
