Used by all? Or only by non-commonsensical people? I'm overstating here surely, but I want to point out that is definition is for a purpose.
People/business/departments who support this purpose will tend to use it - and check some register or student card to verify wether somebody who claims to be a student actually is. Others will simple ask: are you a student? (e.g. for downloading some software) and accept the answer as truth.
