...I find it strange for people being able to beat the casino since this in theory it is totally impossible in the long run.
We should not deny the fact that there are professional players in this industry who, thanks to their card counting skills, regularly win at casinos. And this is the biggest expense item, and accordingly, the casino makes every effort to identify such players with a further ban on casino gaming.
Obviously, that’s why the statement “no one can beat the casinos” doesn’t just fit. Most of the casino games really do make skills useless but, that’s mainly when you’re playing online as there are some casino games where a little bit of skill can work, like blackjack and poker.
Speaking of which, not something I’ve seen personally but, going through social media, you’ll find a few gamblers whose win rate has gotten them bans or restrictions from some casinos. Perhaps they know just how to cheat their way through the system. A good number of them could even put casinos out of business.
It’s rare for these things to happen but, it ain’t a lose for everyone every time.
