The vampire part is a theory based on:

1. Humans are mortal, so they have a limited life force they can refine into mana before it reaches life-threatening levels and the body nopes out on you, leaving you unable to use magic until you renew your life force. The armor used by Freadia Strikers works by tricking the body into thinking it hasn't reached that limit, allowing one to use more mana than normal by burning out their life. However, the limit is still there, so you could end up killing yourself by exhausting all your life force.

2. Vampires are supposed to be immortal. Immortal beings should have infinite life force. Infinite life force equals infinite mana, so they should be able to use all the magic they want without ever running into the body limiter problem.

So basically, as Herald said, normal magicians have a limited mana pool that replenishes over time, vampires supposedly have an endless mana pool.
