All in all, you should never expect anything big in gambling, because the probability of losing is always high in gambling. Whether you have limited money or a lot of money, you can never expect anything big from gambling, it is never the case that you can win only if you have a lot of money, if you have more money, you will gamble more and face more losses. No matter how much money you have, you have to gamble with the amount of money you can afford to lose, and you have to adapt to both outcomes, loss or win. Be satisfied with small wins and accept the losses when you lose, and stop yourself at the right time.
You have to understand that the money in this case, the money won, is not hard earned money so it becomes very easy to play it again and lose practically everything. Honestly this is the main reason.
When you get caught up in gambling and become addicted, it happens because your spirit is out of alignment and this causes imbalances that you try to compensate with the adrenaline of the game.
