Real gamblers blame the outcome of the games on their own decision and not shifting the blame to anybody else. Anybody blaming others should know that the blame won't change the outcome of the bets, they're only wasting time and not ready to become a gambler. When gambling, there are bets that you can't do anything about because no matter how many times you try, you'll end up losing. Haven't you seen a game that no matter what your bet was, it wouldn't had still favoured you.
For me i think it will look very absurd for any gambler to even reason like this, gambling is an individual game, lets not forget that any decision you make while gambling may not really come as you expect it and thats the reason why as gambler who understands what gambling is you should in the first place that there's no one to blame to what happens to your betslip, you lose or win whichever way take it as it is no one has to be blamed but you alone, infact you don't even need to blame yourself when you lose after all no one can say what happens in a bet but as a bettor you must take responsibility of your actions no diversion of blames I think that defines a real gambler.
