It does mean the lootbox mechanic. The term comes from gachapon, Japanese vending machines where you get a small plastic capsule that contains a random figure/toy of some kind. In gaming, the virtual capsule can of course contain anything, such as new characters, recently often anime girls.
I thought gacha referred to the lootbox mechanic, how core are anime girls to gacha gaming? Actually curious.
A lot of gacha games are anime-styled. People spend a lot of money on those rare anime girls.
