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.
A game of chance is an activity which depend on luck or randomness. So when we use fake money to play that game of chance, we need to know that we can curious how it feels when we use real money. So that will attract us to keep playing gambling and deposit because we are curious with the result and we want to feel how if we can win the money. Maybe there will be differences between loot boxes in on place and other places. So that is normal if we see that because they have something that will attract more people to play the games.
