The rich also experience the ups and downs when it comes to gambling. They too do experience defeats and losses on their bets but most times, they wouldn’t be affected by the loss.
They’re rightly concerned about putting money from the meagre amount earned into gambling when they’re more likely to lose that money. Better to utilize it on something better.
The rich don’t have that financial restriction as they’ve got enough money to bet consistently or to stake a bet with high amount periodically.
That's the main advantage the rich has. They can continue to try out their luck in different games but they poor cannot. Simply because the poor are restricted to a certain amount of money. They can't spend as they please. On the other hand the rich has abundant amount of money. So even if they loses 100 bets, it won't be enough to affect them that much. They can just move to another game if they feels like it.
Most people who don't have a lot of money will try to continue gambling because they hope to win some money. They gamble as if they are rich even though they are not, but if they had been gambling for a long time and could calculate how much money they had used, maybe they would be surprised to see the amount of money. That must be a lot of money that they have used for gambling. But that doesn't stop them from continuing to gamble because they still want to win. And it is different from rich people who often gamble because they have more money and sources of income that can provide more money. So we still can't compete with rich people in gambling and we can only gamble moderately rather than lose more money.
That's the mindset that most poor or lower middle class people have, I think the circumstances are the main cause that will push his mind to continue gambling and get a lot of money from winning to improve or increase finances in his life. I think only a few gamblers think to see how much money they have allocated to gambling, because their main focus is only on winning and indirectly it makes them forget about how much money they have lost in their gambling involvement during that time, of course if they see it maybe they will be surprised but that does not mean they will stop or just reduce, there are many choices they can choose between being more aggressive in gambling next with the aim of breaking even or reducing it in terms of budget so that the amount of defeat is not too large.
Honestly, I can't tell if rich people gamble more often than middle to lower class people or if they are very rare because they have a lot of activities in the real world, but what is certain is that as you said, rich people have a good financial level and with that, they have the freedom to put any amount on their gambling, for them winning is normal and losing is also normal, because obviously they already have a place to make money that is like running water, endless as long as they continue their business and that means that maybe losing is not something that matters to them.
