Gambling is no scam because you are aware of what you are doing or game you are playing, in as much as there is an agreement by the two individuals or groups before starting the game or bet it is not. But when you say scam ,the person is not aware of your intention .
Gambling is a game of try your luck ,a game of chance if you can win to make more money or valuables for yourself, getting rich quick.
You are right; gambling can only be said to be a scam if the person is gambling and does not know what gambling is in the first place or if the system turns to scam the person by providing an unfair result to the person. Let's use sports betting for instance, where you can place your bet and know the outcome of the game even before you check your bet result in the casino, or eventually the game result doesn't turn out to be the way it's supposed to in the sports event. That's why someone should accuse the system.
Yup, when things didn't went according to your expected outcome especially when you're done with your research, when you think that everything is moving according to how you expect but it turned against you when the outcome was announce, there are many rumors that circulate and the gambler who lost their bets surely thinks that they've been scam.
But, that's for sure is not new as there are upset that happened and even the heavy favorite loses their game and bring dissapointment to every bettors who believes in them,.
You would really be ending up such conclusion or assumptions that you are dealing up with some scam sites specially if you have done your very best and applying any strategies that you are applying on which you are really that thinking that you might be that being scammed on which this is really that a very normal mindset to have at the time that you do make out such engagement. Whenever you are losing money then you do love on pointing out your fingers on which you've been believing that they are totally fair. This is why there are tons of people or gamblers who are really that pushing their limits and even taking up some loans or borrowing money just for them to chase up into the loses that they are having. They will be having those kind of thinking that they might be that lucky on next time. When they have lost again then they will be trying out to spread up some false accusations that the site or platform isnt fair on which this is totally BS, ruining up someones reputation just because you have lost? This is kind of impulsiveness on which most gamblers do really end up into. If you are that not good when it comes to self control then it will be best or better that you should be wary at least into the actions that you are that into so that you wont be that making yourself that look stupid just because of some false accusations.
