Lolz. This topic is confusing because I can't say yes or no. In some cases it is when you are addicted that they make more money and in some cases it is when you not buy deposit big amount and loss it. Why people becoming addicted to gamble because they want to make more money at all bets or games and the mindset to make more one day even when they are losing is the highest cause of addiction.
"I will win big one day" and I will buy car, build house and give big money to my girlfriend. This is the major thing that making many gamblers to be addicted.
