It's definitely impressive but you also have to consider his style being very simplified as contributing to such an output. Also I'm pretty sure that there are a non-zero amount of pages in his library that he didn't draw for at all. I read a line about this in a volume of the English Yoshiharu Tsuge complete works (think it was Nejishiki), going on about how mangaka like Tezuka and Mizuki had a clear "house style" which led assistants to sometimes have complete control over pages and sequences, in part contributing to those massive body of work.
