You seem to have misread everything by a factor of ten.
Delta IV Heavy's payload is rated at about 50,000 lbs
to LEO, roughly a fifth the payload of a Saturn V.

Future variants of the Delta IV Heavy could eventually
approach the performance of a Saturn V; hopefully at
lower cost. But we're not there yet.
