Before I was trained in scuba, if you asked me what was the oxygen content of air, I probably would have responded "Close to 100%"
And Im not a dummy. I actually knew that air consisted of small % of things like NOx & SOx, as I did some work on air pollution issues. There's just no reason a person in the general public knows the components of air, and specifically the ~78% that is N, as it really doesn't matter to us, unless we're under pressure.
The general public probably thinks of air and oxygen as pretty much the same thing -- I did. I knew that I breathed in air and that my body used oxygen (ergo air and oxygen are pretty much the same thing in my mind) and then I breathed out CO2. No reason for more information.
