Note the comment makes no absolute statement. Note the reference to "odds." This is almost the same idea as: "Remember, most people think they're an above average driver. Also remember, half the people are below average drivers."

It's also along the same lines as, "There's always someone better than you."

Also note the use of "really." "Know" is twice accompanied by the adjective "really." I would've thought this would make it clear that I wasn't talking about "a little knowledge." The odds are that a programmer does have "a little knowledge" about [X].

Given that you, despite claiming to be puzzled didn't try to take "odds" or the frequent use of the adjective into account, I wonder if you are apt to catch details like that. Maybe this would make a good interview question for coders?

     Also remember, half the people are below average drivers.

Depends on what you mean by "average". If you mean "median" you are correct, but if you mean "mean" (like most people do) this is not necessarily true for most interesting situations.

A simple example where most people are above the mean is that most people have an above average number of legs.
