yep, I really understand what you mean and it's the same as making $ 100 from gambling its very easy if become a bookie (gambling owner).
someone who does not understand how gambling works must think something impossible like there must be a way to win every day from gambling with the help of artificial intelligence or using other ways to be able to earn. but in reality gamblers will always lose and casino always wins so I agree with what you said because it makes perfect sense.
And the funny thing is most gamblers don't understand simple things like this that casinos design their games with such low probability that it would be impossible for gamblers to win continuously at that game unless they find a hole in the game. And because of that gamblers must understand that if they want to get a stable income, they should look for other sources of income, which can provide them with a more stable income.
let take the example of one casino game like slot games. we think when we get the first win from the free scatters that we get our minds think if this can be made into income because every slot will definitely give a free scatter from the basic spin and he always bets every day in the long run loses all his savings and gets the win again but if you count the wins and losses they are not balanced.
another example of sports betting, even though several times the predictions are right and win, one day a surprise from the opposing team beats our bet
maybe the gap is by way of arbitrage betting but also the risk of account + money being confiscated by the gambling party.
so no one is safe to get income from gambling 96% lose 4% win and that not guaranteed. so the sane gambler he will look for income elsewhere and think of gambling as a place to seek entertainment a little luxurious just to try their luck.
