Psychologically this is not true at all. It's much easier to take risks when you have nothing to lose.
How many 18-30 year olds do you see having a swing at it and trying something, vs 30+ people with families and savings to burn?

The more relevant question would be, what % of 20-30 and 30-40 year olds start businesses?
I'm not surprised most become successful over 30, it takes time to learn.
There is a sense of urgency (e.g. if I don't do it now I won't get another chance) that counteracts the feeling of "nothing to lose")
