Rich gamblers apart from having the freedom to gamble because they have a lot of money, what determines why rich people can earn more money is the minimum bet is different. if we as a gamblers whose maximum bet is no more than $10-$100, if we win at sports betting with a win of $100 we will be very happy. Meanwhile, rich people can have more betting power than that. If this rich gambler bets $20K, and wins $20K, this is very different from a small gambler. So, it's not surprising that the rich get richer if they win, especially if they get the jackpot.
A rich gambler can bet with the maximum or minimum bet so he can gamble longer than the average gambler and if he wins, he can also win more than the average gambler. That is why most gamblers still often experience defeat and lose all their money in gambling but that does not make them stop their gambling activities. They will keep coming back to the casino to gamble and hope that this time, they can win a lot so that they can recover their previous losses and also earn a lot of money. But a rich gambler who has been gambling for a longer time can get big wins and when he wins, he will probably rest longer than most gamblers, especially if the winnings are very large. Yes, it is not surprising that rich gamblers get richer if they win, while ordinary gamblers only lose more money.
Apart from the rich gamblers are not immune to the risks associated with gambling, They can gain potentially larger winnings that can cover up their losses, because they can put bet after bet due to their capital depth. They also feel less pressure to win that makes them more control of their emotions that makes them better at decisions making. Most of the times, rich gamblers are more rational at gambling.
Gamblers with limited funds may be more inclined to adopt a cautious approach and minimizing their bets, because they have bigger fear of losses. They have budget limit to stick to and bigger pressure on their own, because They need to prevent the negative consequences they can't afford.
You are right in what you say because rich gamblers can win much bigger than most gamblers. They can gamble longer and may be able to win more than most gamblers. I remember there was a rich gambler who placed a bet with big money and when he won, the amount of money became 2x-3x the amount of money he used to place the bet. Indeed, most gamblers can also increase their betting money by winning 2x-3x. But the amount of winnings he gets will be smaller than that of rich gamblers.
That is why the average gambler should not place bets that are more than he can afford because it will make him careful with his money. He can also bet with a minimum bet so that his money will stay supplied so he can also gamble a little longer than usual. And don't follow what rich gamblers do because most gamblers have little money.
