It's not a scam if you are doing it accordingly but when you start exceeding from how you percept things then it's start additional problem to the point that it will be a regretful experienced..
But is still not a scam then if you gamble more than needed

You just get addicted, not scammed
"not a scam when doing accordingly", but what moment gambling turns into scam then? I am really curious when will people stop thinking "losing means being scammed". People should restart their brain and stop expecting every bet to win. Stop blaming and accusing other for their own actions.
