Incorrect.  It is absolutely fucking true.

PDF is derived entirely from PostScript as a SUBSET:

"The PDF and PostScript share the same imaging model and both documents are
mutually convertible to each other. Both documents produce the same result
when printed. The difference between the PDF and PostScript is that the PDF
lacks the general-purpose programming language framework of the PostScript
language."
