Why people call Mags clips?

Also the 'perception' of mags being clips and so on is reality because it is very prolific. Not so much "tec-9 machinegun, m1 garand assault rifle". If I picked a random individual on the street he or she would likely not even know what a tec 9 or a m1 garand is. Also if said person knew of these firearms by name, more likely than not they would know that said firearm is not an mg or assault rifle.

That's not exactly quantifiable.
