I think if you only play for fun no need to spend money, everyone doing a gamble because they want to multiply their money and gain a lot of profit so he can buy a lot of stuff/item.
I do gamble for fun at the most of the time and making money is not my first target of such spending of time. I love to play poker with my friends and here the point is more about chilling and having fun and good conversation instead to make yourself richer through all of them.
