In a new Emacs session,

--8<---------------cut here---------------start------------->8---
(require 'tex)
(length
 (setq TeX-global-input-files
       (mapcar 'list (TeX-search-files-by-type 'texinputs 'global t t))))
--8<---------------cut here---------------end--------------->8---

returns 7452 for me, after opening a LaTeX files its length is 7500,
not much more.  I didn't look for the differences, `cl-set-difference'
could help for this.

I didn't check how those variables are exactly defined, but maybe it's
because `LaTeX-global-class-files' has only class files and
`TeX-global-input-files' all files that can in some way included in a
TeX file?
