Gauss' Law Universally True?

K^2

Seconded. Gauss Law always holds, but it is insufficient to determine the E-field unless you also know the curl of the field. In statics the later is always zero, so Gauss Law is all you need to solve a statics problem. That's probably what Feynman is talking about.
