Hi! How can I say guys without say guys?

Hello! I work in a casino as a delear, but they say that I can't say guys because it sounds informal but you know the casino is not tooooo formal on stake, the cuestion is that I need ways to call the players and I don't want to sound "bored" or not to formal. Tysm 🫶🏻✌🏻(sorry if I had any gramatical mistake🥲)
