Teleport unknown amount of players to a specific area

Question

I'm making a server full of mini-games, and I'm running into small problems on specific games. I got everything set up except for this issue:

In racing games, I'm having trouble teleporting the winner (or top 3, I know how to place them) to a "podium": I don't know how to let the game know how many players there are, and teleport the winners into one area and everybody else into another.

Answer 1

I'm not entirely sure how to fix the first problem but the second one can be solved by using /tag (Insert target selector for winning players) add Winners and then using /tp @a [tag=!Winners] <x,y,z> to teleport the rest of the players. /tag gives a specific data tag to players or entities that helps specify who you want your commands to affect.
