Well, unless you're leaving something out, you just said that the less education a person has, the more capable they are - so, reductio ad absurdum, the most capable people in the world are middle-school drop-outs. But I suspect you're trying to suggest that education and competence are completely uncorrelated (which is a claim that would be hard to back up, incidentally) and that "something else" is an indicator of competence/intelligence/capability, but you're not specifying what you think that is.

Yep. Some of the best people I know either didn't graduate, or graduated in fields more or less entirely unrelated to what they do.
