Gachapon and gambling might prey on the same psychological tendencies humans have, but they are not the same thing, which is the point of my comment.

I fail to see why saying "If you lack self-control, work on improving yourself" is a bad thing to say, or somehow wrong. If you cannot exercise self-control, then you will not have a happy life. You will find yourself constantly broke from impulse spending on things you don't need or that give you no return on value other than "I might miss it." You do not need a gacha game for that, as there are plenty of other things in real life that can do the same thing that people here wouldn't be downvoting or commenting on, for example:

• attending a local farmer's market
• attending live musician performances
• attending a live artist or author event
• eating promotional food items at restaurants
• attending hobby and art conventions

Everything has a time limit. Nothing exists for the span of eternity here, and thus everything has a chance to become, if it is not already, a time limited item or event that preys on FOMO for different personal interests. But if you have self-control, FOMO doesn't have hardly any effect on you. Your do not HAVE to do X, or see Y, or buy Z. It is not a requirement of life. You aren't going to ever be able to do, see, or buy everything you want. Its a fact of life. Self-control helps you realize this.

Saying no to yourself is powerful. You dont always have to say no, but self-control helps you to know when you should. And thus, it removes the power FOMO has over you. You stop caring about what other people think or say, and it gives you the power to stay financially responsible, and helps keep you mentally healthy.

Why is this bad? Even in the context of what I am talking about, if someone decides to play a gacha game, they should definitely have self-control. A person with no self-control will quickly find themselves peniless playing a gacha game, but they were probably going to be peniless eithout the gacha game too. Its not the fault of the game, it is the fault of the player.
