Every single gambler knows that in the long run they are in red yet they keep playing in hopes that they will get that big of a win,it is that that keeps gamblers coming back even when they go bust in a big way by losing a lot of money otherwise they would stop gambling very quickly.No one can make 100 dollars every single day in a casino as this is plain impossible but everybody keeps coming back there to try their luck in a new day and this is what keeps casinos happy as they get money in every day because from 100% of gamblers playing there only 5-10% win something while 90% go bust most of the time.
The only chance someone can make 100 dollars daily is if they play skill games like texas holdem poker or sport betting where 50% of skill is still involved.
You are right, I would say that those who can win really well are even less, maybe it is 1-3%, and the minority is winnings in the casino, and a little more is gambling. Players return to recoup, or for adrenaline if it's just a game in order to distract from work or from the daily routine. I also believe that winning $100 a day is impossible, and if you believe in it, then just try playing for a few months and see for yourself the result.
See yourself and assess if you really got that chance to win in a daily process, I believe also that it can't be done everyday,
maybe you can 3-4 straight days but after that you'll lose it back.
Better to treat gambling as good place to kill some time, for entertainment and not for your daily source of income, in that view the
chance of enjoying would change the view of losing.
Gambling always accompany by risk, it's tough or maybe impossible to keep winning your bet.
