The difference between Homo Magi and Magic Users.
Example being: Zatanna Zatara and John constantine
Homo Magi is a race of human beings who born, quite literally, with magic in their blood. They are magic blooded humans thus making them incredibly powerful, even from birth. This is why it’s so important for them to start their training when they’re young. Zatanna knew how to talk backwards and start to use her magic before she could even tie her shoes, Giovanni made certain of it. It is also through this race of people, that Zatanna has loose ties/relations to Arthur Curry aka Aquaman, as the Homo Magi helped form the basis of Atlantis itself. Cool little fun fact for ya.
Homo Magi Include: Madame Xanadu, Zee, Giovanni, Sindella, Felix Faust, Doctor Mist. (some others but those are off the top of my head.)
Back to my point.
Magic users are those who have learned magic and utilize what they have learned over the years. It’s a taught skill, more than something that they were actually born with.
Magic users: John Constantine, Papa Midnite, Nick Necro, Doctor Fate, Sargon the Sorcerer. (some others but those are off the top of my head.)
