You can always find people both better and worse than you at everything, both from the pool of "amateurs" and from supposed experts. Just a fact of life.
I'll take a bold stance and say right up front that you get out of college what you put into it - If you want, you really can get a solid education even from a crap college; and on the flip side of that, you can sleep your way through quite a few majors and still end up with a degree. That said - On average, I would say a college degree proves one, and only one, thing about you - That you had the ability to learn enough, and follow directions enough, to complete the basic requirements of that degree... And that already puts you in the top third of applicants, even if you smoked your way through a humanities major.
Now, as watered down as that may sound, I don't mean it as quite that weak of a stance - In practice, the real world will never require 90% of what you learned in college, and college didn't teach you 90% of what you need for a real job. College does not, and should not, equal vocational training. It (can) give you the foundation you need to excel, and demonstrates to employers that you at least don't count as a complete waste of flesh. Anything more than that - Pure cake.
