What do you mean by the word equivalent here? It means that it is clear that from the beginning in general everyone must gamble with money from their hard work, you yourself decide to gamble and there is no coercion or even threats from anyone including the casino that tells you to get involved in gambling, so of course it doesn't make sense if you think that the casino has cheated you just because you experience a loss with a possibly quite large amount. On the other hand, I am honestly sure that you will never think that you have been cheated by the casino if for example you managed to win, meaning that the assumption of fraud actually comes from within you because you feel disappointed and emotional because you lost while on the other hand it is clear from the beginning that defeat is part of the consequences when you are involved in this activity.
