I don’t think I’ve ever seen a gambling addict admit the negative consequences of gambling? It seems that the industry has some way of pulling the wool over their eyes so that they cannot see the destruction that awaits them. Personally, I think addiction based gambling is an extremely difficult issue to crack, as it keeps being reinforced with moments of joy (small wins) which somehow balance out the extreme lows (losing big). Personally, I don’t gamble with anything more than $50, and rarely do so even at that, because I know how much of a landslide gambling can turn into.
Addicts rarely do admit the consequences of being addicted to something because they don't want to face it. Talking about it to someone might lead to facing the matter and they probably have tried doing so in the past and have failed, hence, the skepticism. They don't want to touch the topic at all.
Our brain has a 'reward system' which gives us dopamine rush whenever we do something rewarding such as gambling. The dopamine rush that you get from gambling is almost as intense as the dopamine rush that you get from substance (drugs). There are people who do not experience a dopamine rush over normal events unlike other people. They are more prone in becoming a gambling addict than most. Since the dopamine rush in gambling is so high, it's where they have found a way to finally get a dopamine rush. Hence, they eventually become a gambling addict.
The moments of joy doesn't really balance out the extreme lows. It's rather because of the
partial reinforcement effect that makes you keep on betting. When gambling, you don't know when are you going to win but you do know that eventually you are going to win. This makes you think that losing is just a part of what it takes to win and so you continuously gamble until you finally win.
And of course eventually your brain gets used to the dopamine that gambling is giving us. This makes gambling addicts take it to a more extreme level (i.e. gambling with higher bets) just so they can feel that same dopamine rush that they get when they first started gambling.
