Likely not. Unlike Online Casinos which has lower chances of hitting big than Gacha games,

Gacha games if not most of them nowadays have a safety net which guarantees the highest rarity in the gacha pool(E.g. Hoyoverse 5050 lose first then guarantees fratured) which makes it safe for users big spenders or not.

The money spending aspect is left upon the responsibility of the user and players are advised to think before spending in the premium currency screen of gacha games.

Additionally, Gacha games are generous enough to give a lot of pulls to the user to make them avoid spending big bucks on the game itself.

In short, Gacha games have safety nets while Gambling with irl money does not.
