I think it's simply survivorship bias. Thousands of people try this and fail. And occasionally you read an article like this, which is like the one in a million who managed to get lucky with their ideas and manage to make it a success. And I think they underestimate how much luck they had.
Luck is a huge factor for sure but I also think it's not as hard as you're making it out to be if you set yourself up for success.
I have four products that make money, built over the course of seven years. None of them really benefit from each other. If it was pure luck and 1/1,000 chance of success I don't think my current portfolio would be possible. (I also have a lot of failures, so I agree there's luck and risk, just not as strong as you're making it out to be)
