No man can control himself completely. Addiction is just scary because no one can notice how much he is already addicted to gambling or other gambling. For example, the inability to promise yourself not to gamble for a while, for a year, may be the initial sign of gambling addiction. Therefore, you need not only to be able to analyze yourself, but also to share your inner state with other people.
I beg to disagree.
People can master controlling their emotions and urges. We are the highest form of being in the planet and we have the capability to think and analyze the things we will do. Every actions that a gambler will make is a result of his own judgment. If a gambler will decide to gamble for fun, it's because he wants to relax and have a hobby to destress from the toxicity happening around. He will not go overboard if he is disciplined enough to know the repercussions of gambling once he go past his limits.
But if a person doesn't really want to make a difference, do not strive to have a goal in mind or a reason why he is gambling, the probability of him overspending and frequently playing more often than what's supposed to will probably what will happen. As a result, he could fall into addiction that's very challenging to recover from if a person is not willing enough. Relapse could also happen because of weak self-control. Which is why it's still better to prevent addiction from happening rather than curing it once it sets on.
So if any newbie is lurking around here that is curious to gamble, remember to be firm to your limitations and do not sacrifice your discipline and good gambling attitude.
