I really like that framing for it. "Won the lottery." Some fortunate circumstances and some choices and his work in those circumstances worked out bafflingly well for him. I love what he's created, and I know some of that success is because it hit a certain fandom critical mass where things kept building on peoples' enthusiasm. It's not a model the rest of us can emulate with any real expectation of it working out the same - not with any more likelihood than lottery tickets begetting financial security.
