'Mage' basically meant any person that hailed from the Watchtowers in either the Supernal Realms or (its profane mimicry) in the Abyss
For completeness' sake: in the old World of Darkness, mages had both similar and also widely different concept. The similarities are that they wield true magick, and to do that they also Awaken. The difference is that there isn't an objective higher magic that has always existed, but rather, they get their power from within. Once Awakened, they can literally shape the world to their will.
In both settings and Sleeper could Awaken and their ultimate goal (more or less universally) is Ascension, the differences lies in between and it's more conceptual - in old Mage, willworkers chant spells or draw circles, or use amazingly advanced gadgets because this helps them focus their power to change the world. In new Mage, they could do the same, but it helps them because it improves the connection to the Supernal realms and thus makes channeling the true laws of the universe easier.
And here is another fundamental difference between the two settings - in both, the mages are "suppressed" for a lack of a better shared description of their situation. In nWoD they are trapped in a false reality[footnote]what can, somewhat accurately, be described by picturing the Matrix. Only once you get out, you get magical powers.[/footnote] while the ones in oWoD are trapped in a reality that is...well, all too real, actually, yet it doesn't fit their type of spellcasting. In both cases this means that when a mage throws a fireball that's an Incorrect Thing, according to the cosmos and usually Bad Things Happen. In nWoD, that's due to the Exarchs who erected the Lie in the first place in order to trap humanity there, while they wanted to have all magic for their selves. In oWoD, it's because in the late Medieval period, a group of mages wanted to
protect the world from the supernatural, so...they managed to convince everybody that it didn't exist - the nature of Reality is that it can be reshaped by anybody, the majority of the population who are unAwakened, essentially outvote the Awakened.

That being said, you had 'gutter mages' who derived their magical power from entirely unawakened means.
These would be a variety of users of Low magic - there are a bunch of them, including Thaumaturges cultists of (essentially) Cthulhu, some immortals and others. They all circumvent the Supernal magic by tapping into powers available in the Lie.
In old World of Darkness, mortal mages were (mostly) called sorcerers or hedge mages. They were not too dissimilar to Thaumaturges from nWoD - they get their power by exploiting existing laws in the world. The difference between them and the Awakened is perhaps subtle from the outside (they would both wave their hands and produce a strange effect) but their powers work fundamentally different. Imagine a sorcerer and a mage need some money, and decide to get some from a person. Let that person represent the universe. A sorcerer would ask politely, for which they may get some change, while a mage would mug the guy. That's more or less the essential difference - sorcerers know specific actions which would yield some result, while mages do actions to distract the universe as they transform the universe into the desired result. This makes Awakened magick far more potent...and far more dangerous, too, as the universe itself snaps back at them when they push it.
