The statement does exist, but the reality is somewhat different!
Ripple free d.c. does exist, but not from cheap sources like "wall wart" chargers for phones & the like.

As an apprentice I loved watching our mercury arc rectifiers working hard. Probably why my eyes are so screwed up now.
I’m rewriting the stuff on power rectifiers
Rotary converters
Mercury arc rectifiers
Mercury arc thyratron
Selenium and germanium dry plate rectifiers.
The boring solid state carp
It’s going to take me a while
No longer there X(

We used to have mercury ignitrons on a multi-spot welder. It is a pity it was scrapped five years ago, i could have got you a photo.
Word got out I was the see the works manager about donating the MAR’s to Manchester science museum. Out of pure spite the charge hand put a sledgehammer through them. The manager agreed they should be saved but the deed had been done while I was in the office. A bit of our history wrecked for 30lb of mercury!
London science museum has exactly the same model as ours.
