In my opinion, all bets are not wasted these usually depend on the bets of the casino sites the chances of winning here are very high if you bet correctly. Casino high or low payout ratio slots with higher payout ratios offer more frequent and regular wins conversely, slots with lower payout ratios have lower winning odds. In casinos the sites should be thoroughly researched before joining. Most casinos will pretend to protect you from losses by offering loyalty programs you can enroll in a cashback program where you can earn points for every lost bet.
I want to agree with you. But if we all win - the casino - lose. And if the casino lose they close - no one will work at a loss. But i don`t hear that casino closing due to gamblers winning.
The same time we can see the thread here, how the gambler lost $1.4million with the odd less than 1.01.
I think that it is possible to win the casino, but you must have a strategy, money management and think about gambling like about job - no emotions, only hard work.
