Making a round system in PlayerGui?

Hello! I'm trying to make a rounds system. For that, I need a normal script because every round you get gear. If I use a LocalScript, the gear doesn't work well. The rounds will be working well for the first player, but I need to be universal for every player, so one option will be inserting the script in ServerScriptService, but I can't have any access to the Player. To fix this, I thought that I can try to get the player name when getting the gear, but how can I get the player name in a normal script in ServerScriptService?

If you can tell me something to change in the script to get the player name, answer this question.
