Maybe they will try playing just out of curiosity, but if it does not work out, they will quickly give it up. Rich people think in terms of money and are very good at assessing risks. That is why such a risky and complicated way as gambling is something they will most likely just exclude from their lives.
Yes, a rich person doesn't fall into temptations like those, the casino is a place where we can be people who lose money, even so we do it because first we like it and second because we don't rule out having some luck and multiplying what we have, but the reality is harsh and it's that you don't win all the time, you lose a lot and based on that is why the rich don't fall into those things, they are more concerned with making their money continue to grow.
