Actually not impossible. The 'impossible' claim assumes a normal distribution (that is, the bell-shaped curve). If instead you have most people being fairly competent, but a small fraction being really, really bad, then most are above average.
Maybe a different example would make it clearer. Bill Gates' net worth is roughly $50 billion. Put him in a room with 49 homeless people, and make the claim that the average wealth of people in the room is $1 billion :-)
