Well I can think of three counterexamples at least,
1. Li Ka-shing didn't even have a formal school education,
2. Bill Gates is a college droupout,
3. Richard Branson is a secondary school dropout

That's why we teach course in Staistics. You can find many examples of anything to support whatever argument or hypothesis you put forward.
You can find an agnostic Liberal homosexual who voted for GWB, but statistics would show that over the entire population of agnostic Liberal homosexuals,the vast majority voted for Alfred E Newman.
IOW - the exceptions prove the rule.

The statistics you showed show a rather weak correlations. Most people with an IQ of over 120 earn at about the same level as most who have an IQ of 100.
