100.% (with a decimal before the percent sign) would be three. 100% with no decimal is one.
I’d consider numbers such as “100” to be ambiguous between one, two or three significant digits. As for “literally”...
Still, I’d bet that at least 99.5% of people alive now have done something which is technically illegal in their jurisdiction. (Not sure about “who ever lived”, though.)
