It does in Musk's case. Why not read a biography of him? It's more interesting than speculation.
Personally, I don't have any view on whether that is correct or not but it's obviously the claim that was made. It seems plausible but I'd want to see some actual data to believe it, not just anecdotes about a few of the most famous founders. Your points about low wage jobs and other trillion dollar companies are simply not relevant to it, and if biographies of Elon Musk contain information that would refute it you haven't said what or how.
Knowing you are an extremely accomplished man and fully capable of parsing this, I have to wonder why you seem blind to it.
I think the point people are making about the low wage jobs is that it's irrelevant. People from wealthy backgrounds take low paid jobs sometimes, so having done so doesn't imply he's a rags-to-riches story.
