While your statement is correct, it is also irrelevant to the current subject.

I am a genre pedant, probably more of one than you are.

Vampire Survivors is not a bullet hell, nor is it a survival game. It is a “survivors” game, called as such because Vampire Survivors is the game that inspired the genre. There are some elements in common with bullet hell games, hence why survivors games can also be called “bullet heaven”. It’s not that confusing.
