The logic behind patience in gambling is that if you end up gambling all of your money all at once then there is a good chance that you will end up losing it all very quickly as well. What you need to do however is simply just focus on gambling a small amount for a very long time, that way instead of losing it all at once, you will lose it a lot less quicker, having a bit of wins at the same time.
For example, if I gamble on a slot today and put 1000 dollar in there, then I have a chance to lose it all in the first bet ever, whereas if I put 1$ in there, that would be 1000 bets minimum, and we all know you will have some wins along the way so there will be at least 2000 bets and maybe even as much as 5k-10k bets with that logic as well, and you could earn while you are gambling and get lucky and have like some 800x situation going as well. It gives you a better shot at it.
See, $1000 is equal of $1 for some people, that's the difference. There are some people who spend nothing at all for fun because they just can't afford, there are some people who spend $100-200 a month for fun and there are some people who spend thousands a month for personal fun. There is a same difference in gambling, there are people who leave million in one night in casinos and there are people who badly cry when they lose $5 in casinos.
But you are right, if an average person wants to have fun, then a one-time $1000 bet is a VA bank, it's far from fun when the result is either win or lose.
I think everyone has to acknowledge that the money they have dedicated for gambling mustn't be more than they are willing to lose and try their best to do low bets and just get the fun from gambling. If they are lucky, their low bets will still give them some profit and the positive thing is that they won't go bankrupt in a seconds.
