That is called gamblers fallacy in literature. If you wagered on 50% chance to win and lost, you could do that 20 times in a row and lose 20 times in a row and that 21st one is still 50% chance to lose, just because you lost 20 times doesn't mean that you are going to be suddenly winning because there is no "I can't be losing 21 times in a row", you very well can, you can lose 100 times in a row as well, it is all possible, obviously unlikely but still quite possible and each bet is individual to it is own and doesn't change depending on the previous bet.
But, most gamblers unfortunately feel like they have lost too many times in a row so they could just end up winning in the next few bets because "they can't be losing this many times in a row!" and they even go as further as blaming the casino to be a fake one and scamming people because they ended up losing.
The feeling that you think in your next roll you'll be able to win it back since you already have a lots of reds. Very common and the worse thing to happened is for some gamblers who will yolo out thinking that luck might be there to back them up and allow the win.
Ending, losing everything and frustrate yourself. Gambling should be more on the entertaining part and not to focus for making money,
though there are gamblers who treat this as a job, but if you aimed to enjoy those wagered money is much easier to forget.
