Humans are to magic what sponges are to physiological structure.
They don't have cores or veins, or any features adapted to making use of magic. They do, however, produce magic; in fact, humans are a little odd in that they basically bleed magic everywhere when they're in high emotions. This probably originated as a panic response that could scramble the spell attempts of predatory magical creatures, and it's worked pretty well for them into the present day. It draws Pokemon to them, lets them study magic without having any natural ability to begin with...so on and so forth.
Without the usual structures for storing magic in the body, humans on a diagram would look like person-shaped clouds of magic. Magic rests at a low density in the tissues of their bodies, and any excess simply bleeds off.
