Misconception which you wrote about is a result of lack of genuine information and knowledge about gambling before joining the niche. On the venture to decrease addiction rate, gamblers are meant to be advised on the importance of gambling. And, also, what they could learn through the game. Gambling has never been a negative activity all through. The problem has to do with the player's mind set. They think gambling is an activity that could ruin their financial life, that's why it ends up ruining their gambling journey on the long run. So, it's actually a nice point referring to gamblers as people who should focus more on being educated about what they're about to go into.
Yeah, there are some who got influenced from thier friends or relatives some who thinks that they can use this venue to find some entertainment but due to a careless anticipation they ended up being addicted, same with what you said, it's better to study and know how you can handle the risk against the potentials, if you just push your way thinking that gambling is a quick way to earn, you may ended up losing a lot.
If you fall to this kind of mindset, most probably you'll end yourself ruining your life getting addicted and losing most if not all of your money.
