If you have the right input luck, there’s a huge number of small $1-10m annual revenue businesses that can be built. Personally, I can’t do all of them for time constraints so have to focus. I would agree with output luck to some degree with some of the biggest outliers (Facebook, Google) but for some entrepreneurs they have made giant wins not once but repeatedly. Bezos, Buffet, and Musk come to mind - and the fact that in all three of those cases you have abnormally healthy people able to handle stress and work load levels that most of us (including me) can’t take.
