So, it depends on one's financial ability and their mindset about gambling in general, and that mindset is often a result of the financial capabilities of a person, which means that if you are rich and can afford it, you will just enjoy gambling, but if you are not rich and still gambling, it means you are looking for money through it.
I fully agree wit you, there are rich as there are poor people that enjoy gambling. It doesn't really depend on how much money we have, because gambling is usually possible and small sizes. So, everybody can choose how much money he is willing to bet with. Rich people have the exact same winning chances that we have, the only difference is that their bankroll is larger and they are not at risk to go broke so quickly. I believe the fun and excitement from gambling is not connected to our own personal financial situation. Also, just visiting a physical casino can be a lot of fun without betting a lot of money ourselves. Usually people like to drink and gamble, because alcohol is either free or cheap at the casinos. The company we are with at the casinos is also important for having a good time. Just because I lost some money doesn't mean the night was a complete failure if I am with my best friends.
