AS my earlier post and link says, 95% of them fail. the word is not "might fail" , it is "probably fail", with a 95% probability of failing. The numbers speak for themselves, and they have been at a 95% failure rate for decades.
You have one chance in 20 of actually making it in a small business, and 19 out of 20 that you will go out of business.
For an older worker of 40 or above, who lost his job to foreign outsourcing and free trade, he will have better odds gambling whatever retirement money he has left, in Las Vegas than in starting his own business. Las vegas odds are closer to 50%, nearly 10 times the chance he has in starting his own business.
