I thought so.

OK - you have pdflatex in the terminal? If yes, you have to bring the
PATH from the terminal into emacs. I use

I use the package exec-path-from-shell for this (and use-package in general):

--8<---------------cut here---------------start------------->8---
(use-package exec-path-from-shell
  :ensure t
  :config 
  (exec-path-from-shell-initialize)
  (exec-path-from-shell-copy-env "LC_ALL")
  (exec-path-from-shell-copy-env "LANG")
  )
--8<---------------cut here---------------end--------------->8---

so
--8<---------------cut here---------------start------------->8---
(require 'exec-path-to-shell)
(exec-path-from-shell-initialize)
--8<---------------cut here---------------end--------------->8---

should do this.

Cheers,

Rainer
