They cite lack of capital. I take that to mean they ran out of money. They'd do that if they didn't know what they are doing, so I suspect you're right. Many, many people are very good at what they do. Being good at what you do doesn't actually equate to having good business sense or management skills. Being an expert craftsman doesn't mean they know how to find customers, read contracts, deal with logistics, hire employees, manage money, or any number of things. When people ask how I managed to start my business and keep it successful, I usually tell them that it was mostly dumb luck. I was just getting good at it, some fifteen years later, when I sold it. There was lots of work involved, but a whole lot of luck.
