In my view, gaming has nothing to do with gambling. This can also be the pitfall for gamers, who think they have an advantage because of their gaming experience. If you're really going to gamble, it doesn't matter how much experience you have in gaming. We all know you're not going to make it against a casino in the end. With gaming you are in principle in control and you are responsible for the end result through your own input. That is not the case at all at a casino. There are also many gamers who have tried their luck at poker, but most without success.
But gamers will have the background, especially in the MMORPG realm like what I and @Boristhecat are discussing when it comes to the gamble of wish or pulling of premium items, in-game purchases that are paid in real cash.
One known game is Genshin Impact which is supportedly widely because of how cool the game is. I also spend some money on it thinking I could get a better item to swap my old one or better, a new character that would help me advance faster in the game.
That's a gamble. It's like rolling a dice to the unknown, then you would have to roll it again (spend more) if you won't have it at your first roll.
Essentially the OP is asking about games that already have a gambling element, and it is clear that the transition from games that contain a gambling element to games that are completely gambling is very simple.
If we transfer the discussion to other games where the risk is choosing strategies/counter strategies to what the opponent is doing, then this is really a different type of risk and I do not think that it will lead the gamer to gambling.
Thanks for pointing that out. I thought we got deeper.
