If you mean by all their customers taken together, then you are right. But how does this apply to us individual players? It's a false statement that "no one can beat the casino". You know this, right? There are tons of examples of people winning huge amounts through gambling, so, I think, we shouldn't repeat this false statement over and over like a mantra. Leave it to dishonest journalists.
I understand what you're saying but here what I mean is about luck and as I said before that there are no guarantees.
what I say is maybe some people will disagree, but from my experience, if I tell the truth, I think someone who wins a lot of money from gambling, if you calculate the overall losses and profits, will not be equal.
like for example I bet the first day I lost $500, the second day I lost $1000 and the third day I won $1000. despite getting a $1000 win but a $500 loss.
but back to that there are no guarantees because the luck of every gambler is different and all of this depends on a commitment not to be greedy. even though someone is lucky to beat the casino make a lot of money but greedy want to earn more I'm sure he will lose even more soon and fail to beat the casino like the problem of that time a person won over $500k but wanted to win $1m and finally all his big win was gone and failed to beat the casino.
