We still have some other people who take gambling as a way of having fun and not all about the money they can win from playing in a casino, while some other people take gambling as a mean of making passive income and this kind of mindset has led many to loses and possibly becoming addicted.
I think that there are more people who perceive gambling as just a way of entertainment and fun than those players who want to earn money by gambling.
We must take into account that over the past few decades, the general level of knowledge of people around the world has increased significantly due to the Internet. And most people know perfectly well that it is impossible to make money on gambling all the time. Anyway, at some point, such a player will lose everything.
And this information, of course, reduced the number of players who want to get rich by gambling.
