You are absolutely right because Rich people are always able and capable of providing for them self when they lose a huge amount in their gambling bet although while the poor people can not provide for them self when they lose a huge amount in their gambling bet, so that's while is not good for the poor people to use a huge amount in their gambling bet just bet as you can lose.
Rich people can have money even if they lose in gambling because they still have more money in their account but that will not be a good idea if that rich people use much money to playing gambling. They must consider that gambling is just fun activity and not a place to makes money. The rich win gambling more than the poor is because rich people can place a bet using big money while poor people can't do that. But if we talk about the lose that they can gets, both rich and poor people can gets the big lose although they have the same chance to win some money. Both rich and poor people must not use much money to playing gambling because gambling can takes all of their money shortly. If both rich and poor people can use gambling with right, they will not lose much money but they will enjoy their time to playing gambling.
the size of the money bet by rich people and poor people will be different. because everyone has different ability limits to bet on.
the chances of winning for everyone are the same. the difference is that maybe rich people with big bets can get big wins. and a poor man with a small bet will get a small win.
rich people can play longer with smaller bets. but it can also be shorter if the betting is very blind. actually, both are the same. but I don't know how often gamblers bet on middle-to-lower economic groups.
People with small finances can also enjoy gambling. so victory is not reserved for the rich only. anyone who bet has a chance to win.
