Yes, it's blind betting, especially on casino games and slots. We only rely on what the system will give us and hope that it will be enough to make us walk away and enjoy all the winnings that we get. I did experience that before and I can it's so satisfying. This is where it goes wrong after you taste the win, you want more of it and so you gamble again. That's also when we don't care if we are blindly betting because we just want to experience more of what we have tasted.
It's easier to walk away if it is a big win, but small multiplier wins could sometimes also be considered as a good win and yet we continue on until we lose it all. It will all depend on the gambler, some just want a high multiplier before they withdraw while others are satisfied with small wins.
Everything is built so that the player never leaves gambling, if one day he can win a big win, then he will become a hostage of gambling because he will wait for another such win and will continue to play, or if there are many losses, then there will be a desire to get back what he lost and will also not want to stop. I do not know if there are players who managed to beat the casino in the end, even temporary successes do not guarantee anything, probably you need to be a genius for this to be possible.
I believe what you said here and that is what happens in most cases, winnings is just like a strategy to make you feel that you have gotten an income generating platform where you can easily make money because when you win in gambling, the money looks like a give-away cash so someone who doesn't apply wisdom after winning can still end up losing everything because they will feel that if they gamble more they will have the possibility of winning more and in the quest to pursue more wins, more losses are being incurred and while trying to chase the losses, further losses is experienced so it's just like a trap when you win in gambling but for someone who has lost money in gambling can decide to quit in order not to lose further but winnings attracts people more to gambling and that is why some people entered into gambling because they heard a news about someone who won huge amount, so they basically start gambling if they can get lucky as well.
Even if there are those who claims to be genius or experts in gambling, they don't win all the time and the only time anybody can claim they beat a casino is when they win huge amount of money and quit gambling completely which many people even finds it difficult to quit after a huge win because they will feel they now have enough money to gamble more with the idea that even if they lose, it's the money they got from the casino and not their own personal money.
