If we take the story from the average gambler's side, they may find it difficult to become responsible gamblers because from the start they have the desire to make a lot of money so they are out of control and they feel how easy it is to earn money just by sitting and playing games (if they are lucky) so that over time they become addicted, just like the point you mentioned about passive smokers, if they have become passive smokers, it will be difficult to stop, but if they have the intention to be responsible, that desire will overcome their addiction, but gradually.
