Winning a $100 daily from casinos may not be that much and it's kind of quite low to be honest but that's not the whole picture as there will be some instances that you might cross over a $100 in your hands but as expected, you will not call it a day because for the most gamblers, that will not be enough as humans will always want more. And in the end of the day, they will find themselves in a situation where they don't even have a clean $20 profit or worse might've gone overboard than the supposed budget.
even for a person who plays with 10,000$ in the casino games with the lowest multiplier, to reduce the risk of losing and slightly increase the chances of winning even so that person will not win 100$ every day, it is enough for that person to lose only a single time 10,000$ so that even if that person earns 100$ in 5 days that even with these earnings that person will not be able to recover the 10,000$ of loss and if he has more loss than 10,000$ then it will be more difficult to recover the loss. so thinking about daily earnings is an illusion, the more money the person plays, the more money the person bets, the higher the losses will be
that's why people shouldn't look at daily or monthly earnings, they shouldn't think about goals when they play, that's because thinking about a goal like for example thinking that they should earn 1000$ in a month, that person will start playing without having control of bankroll management and will not be looking at the losses, let's imagine that a person sets 1000$ per month as a goal, that person starts to bet every day and loses a lot, but on some day of the month he wins 1000$, that person will be happy but you will forget that you had losses that far exceed the 1000$ you won
this has happened to many people, and that is why some people are playing with a very high multiplier because in case of a victory, they manage to recover all the money they lost and also manage to make a profit, the same scenario can be seen in sports betting, in that some people prefer to make multibet bets because with that when they hit they win a lot to the point that they can lose for a few more games that still remain profitable. also another strategy consists of making many single bets with odds above 1.50, if the person hits many bets then he will make a profit
