Playing cards with friends at someone's house when everyone gathers is fun, right? We can play for pennies or we can bet nothing at all, it doesn't matter how we spent this time. For example, watching football when your favorite club is playing and betting on various events: a goal in the first half, the score, etc. is entertainment. Everything comes down to money, if you set the goal of earning a lot and at the same time taking risks, this is not entertainment.
I have periods when I can not play for months because I just do not have enough time, and meeting with friends to play games is really fun because there is no goal to earn money.
