Have a couple old pirated e-textbooks as .pdf files on my PC from uni, several hundred pages with color images, and they are mostly under 50MB, averaging about 30MB. 1GB is a little over a thousand MB (1024) so 1 would maybe hold a bit under 50 or so each? So times 64 that, a hell of a lot. Several thousand total, at least, as size varies.
No actually I agree with you, plus PDF is a privacy and security nightmare allowing for arbitrary JavaScript execution by default if you don’t limit its permissions. but unfortunately it was all that I could find of that ISBN so it was either shut up and use them or pay full price for my textbooks, so, y’know, I sort of grit my teeth and went with it.

PDF is super overkill for ebooks. Mobi or epub are usually <5mb per book (usually around 1mb)
