Google is taking over more and more profitable serps with their own properties (adwords/local results/maps/lead gen etc.) and pushing organic down unbelievably far on some queries. I don't doubt those reports.
However, since these are averages, I think it is so query and serp dependent as to not be all that useful. That old AOL report was such a rough guideline and got boosted as gospel across all serps/queries which was bogus. Think of all the factors that go into what a person clicks on in a serp.
