There is a subtle (perhaps unintentional) sleight of hand here.
60% of all new restaurants close on the first year. That is very different than half of *all restaurants, even those that have been open for decades, closing in a single year.

I think the more important distinction is that this is 60% of ALL restaurants, not 60% of the 10% of new restaurants (or 6% of restaurants).
(I made up the 10%, but I'm sure it is small.)
