I think the original poster just means that, compared to other industries, the odds of success starting a software company (especially a bootstrapped business or consulting business) is a lot higher than other industries. I'd take software odds over the odds of starting a restaurant that succeeds any day.
Yep - and with that I completely agree -- just wanted to convey that the odds aren't like... 9/10 succeed, but like you said, it's waaaaay better than starting just about any other type of business
