Slight of Hand in a World of Wonders

I have been thinking and wondering what it means for stage magicians if magic were real and commonly known to be real. Would there be stage magicians or would they be mostly replaced by real magicians using real magic upon the stage? Would language more clearly articulate a difference between legerdemain/stage craft and using real magic? Ultimately I have to go with what makes for a interesting and believable setting without going into deep detail, this after all is a fun question that I probably won't actually use in a story. All of this is just background to know if having a character refer to David Copperfield makes sense or not.
