If it makes you feel better, my sense from what I've read is that you're more likely to have success once you get funding. You've been through a lot of pain, and you still believe in yourself and what you're doing. And apparently some very experienced and talented people believe in you too. That says a lot.
As for the "Somebodies", it's not all about past success; there is a lot of luck and flair to it. There are, in any human culture, people who are utterly worthless but can make the magic happen. They don't know much technically, but they're great at using the herd mentality and certain exploitable vulnerabilities in weak minds in order to make other people like them, so getting funding and press comes easily to them. When they actually have to build a product and a team and a company, they're screwed, and they tend to flame out catastrophically. Whereas the people who actually work hard and have real capability will have slower paths to success but, when they get there, they'll be able to stay where they are because they've actually earned it.
