How much does celebs spend on playing at casinos?

Celebs get almost everything for free from fashion needs like clothes to bags and so many more. It made me wonder if they almost get anything for free, what else would they do with their money? I guess some would bring it to Vegas and spend it there. Or if they are too busy, there’s an alternative to Vegas, one could also play at online casinos for real money nowadays. I wonder how much would they normally spend on a night….
