That might have been true locally, but you need to know the actual lead levels (which can change with infrastructure changes) in cold and hot water to know for sure. I replaced my hot water heater and supply pipes myself, so it has no more lead than the cold. They're currently tearing up my street to replace the lead in supply lines, so... everything will hopefully improve here.
