It is also true that even in Webmaster Tools you may only see a sampling of your backlinks, but it is a MUCH more complete sampling than you get with the link: operator. You sometimes also see links that are no-followed by the linking website. This doesn't mean those links "count", just that Google is telling you they exist.
So the reports that Google offers (both the special operators and WMT) do not come "directly" from the ranking algorithm's "working" data. The report data is accessed in a different way by the Webmaster Tools infrastructure.
