So my second question is, is it really compulsory as a gambler to take a high risk by gambling with money that isn't yours[/b]? .....
If a gambler suddenly wins on their first bet, the chances are high that their addiction will spiral out of control. Imagine this: this guy simply placed a bet, without thinking twice, and won real money. Money he'd previously only seen every month after hard work.
Now, suddenly, he receives a huge sum and can solve problems he hadn't expected to solve yet. He can buy electronics, fix his car, or get his teeth fixed. The casino has effectively saved him, and of course, this positive effect psychologically binds the gambler to the casino.
