Obviously there are exceptions to this rule. People have beat the casino. I’ve seen it happen. There are plenty of people who won giant jackpots. However, that doesn’t mean it is possible for everyone. A lot of people have to lose to the casino for one person to win. Don’t fool yourself into thinking you will be the one.
I think when we are talking about beating the casino in this context it means being profitable in the long run... it's possible to win out of luck one or two times, you witnessed people hitting the jackpot, this is very normal but It rarely happens...The problem with this is that you can't win constantly if you are a regular player, the people you witnessed winning huge amounts are bound to lose more than that if they continue gambling that's just how the game works
