they are (if we ignore the "variables" word in your question).
but so are signals and tables and whatnot.
they do not reference "arbitrary" memory locations (as you might expect from
the name "pointer").
if you look at the implementation of Pd, then they (of course) are real
pointers, but that is abstracted away (and not accessible) when working on a
patch level.
some externals might be tempted to use the A_POINTER atom for generic pointers,
but that is actually a bad idea.
