I was having a conversation about gambling with two young men and one of them said gambling is not for the poor people, that it has the proclivity to favour rich people much than with the poor, and the examples he gave made me to come close to endorsing his interpretation.
His argument is that the rich people gambling do not have to pack a lot of odds as in parlay bet to accumulate a high odd size that will give a satisfying potential win. The rich has the money to risk huge amount to a single game for instance 2 odds staked with $1 million to win $2 millions, but the poor staking with $100 to win $2 million has to pick multiple legs to accumulate odds to get such potential win. It hence decreases the gambling winning chance whilst the rich gambler chance remains increased.
Gambling is for both the poor and the rich but bets are different for each other. I can bet as low as 0.10 cents on sportsbook websites. Rich can bet as high as 50000 USD on a sportsbook. Our bets can be proportional to our wealth. If poor person tries and places a thousand-dollar bet, then they are playing with their fate, they might win or lose everything but rich people with millions of dollars won't lose much because casinos have set a higher limit and 50K USD is not much for a millionaire or a billionaire, that's the only difference between poor and rich.
Overall, gambling favours smart people, especially those who are for fun and not for profit, who do not build gambling strategies and follow their luck with responsible budgeting.
