But if you buy the loot game with fake money or in game money then I would say I don't consider that as gambling
I disagree with you because a game of chance is an activity in which the outcome largely depends on luck or randomness, rather than the player's skill, strategy, or knowledge. While many traditional games of chance involve betting money, it is also possible to enjoy such games without involving real money, which can still lead to addiction. I believe the key point is that loot boxes still lack studies and regulations in most countries.
