Well, `add-to-list' adds a single element to a list but you provide a
list of many elements which will be treated as one element and has the
wrong format then.

This works:

--8<---------------cut here---------------start------------->8---
(require 'tex-mode)
(dolist (el '(("\\setN" . ?ℕ)
              ("\\setP" . ?ℙ)
              ("\\setR" . ?ℝ)
              ("\\setZ" . ?ℤ)))
  (add-to-list 'tex--prettify-symbols-alist el))
--8<---------------cut here---------------end--------------->8---

No, it is an normal alist, so many-to-many with first one wins.
