[DC] Does every human have the potential to learn magic? Is human magic in any way different from alien magic? Do many of the other various sentient species in the universe even use magic, or is that just a human thing?

There’s Homo Magi, who are humans with Innate magic powers. They’re basically magic mutants, where they’re normal people until their magic is triggered, like Zatanna.

Then there’s those who tap into objects of power, like Doctor Fate.

Then there’s those who made deals with demons, like Constantine.

There’s people who are half-human/half-magical being, like Tim Hunter.

Then there’s those who are changed in some way, like Swamp Thing, Shazam, or Etrigan.

Basically, anyone could use magic if they had one of these things, but as not everyone has the helm of fate ... not everyone can use magic. Although all Atlanteans could. Atlanteans are pretty much all homo-magi who just haven’t been activated.
