The books don't give much distinction on the matter. In The Red Pyramid, when Amos takes Carter and Sadie to Brooklyn House for the first time, he explains that mortals cannot see the mansion because their minds cannot comprehend magic. In the CHB series, this is the Mist at work, and The Crown of Ptolemy confirms that the Mist and the Duat are connected. All this seems to suggest that magicians are not entirely human, like demigods.

Later, however, we learn that only certain magicians have the blood of pharaohs, and the rest are simply humans who know how to work magic. This begs the question: if the majority of magicians are in fact just humans, how can they see through the Mist? The chances that every magician happen to have clear sight is too big of a coincidence for it to be possible.
