If you have thousands of dollars to invest and want to do no work, just buy index funds.
The problem, though, is the risk goes up with the potential reward. Your chances of winning the lottery are indistinguishable from zero. But it's still there.

Sounds like your contradicting yourself. Sounds like index funds are in fact a free lunch.
I created my company, but I knew the market from inside (it wasn’t a public company so it wasn’t insider trading, but clearly I had unfair advantage at start). I’ve witnessed many people on the same market as I was, trying to find something to sell, and failing at it. Everyone here is told that they can do it and the good idea will arrive as they work, well, that is spam. Truth is there are enough businesses in the world.
It’s not exactly just luck. It’s also accurately knowing when you have a chance. I’ve also witnessed a dozen startups succeed in my area, to the point of about $50m revenue, so I could also have succeeded better.
But really, it wasn’t your skills or your confidence. It’s that you didn’t have a good edge at start, maybe your only flaw is not judging against your initial idea, early enough, and waiting for the next opportunity in your professional life. But your implementation skills are visibly excellent, so if you don’t feel like restarting on your own, go help someone and help him scale. You’ll be excellent at it.
