I don't think people are arguing Gates didn't do anything to warrant his success, but they are saying that if he hadn't been afforded early opportunities significantly more advanced than perhaps 99% of other high schoolers in the US, or 99.999% of other high schoolers in the world (and I don't think that's an exaggeration - seriously, search for articles about how his HS computer system was networked in with U of Washington ... in the early 70s), that he wouldn't have been nearly as successful.
