Remember to cover the basics, that is, what you expected to happen and
what in fact did happen. You don't know how to make a good report? See

* Introduction
This bug report show examples where it is noticeable that =org-element-map=, when =link= is the value for the =TYPES= argument, doesn't consider all links in the current buffer.
* Examples without errors

This section show examples where =org-element-map= correctly iterates through all links.
The following is an example.
#+begin_src elisp
(let ((lines '("|-----------------------|"
"| [[https://link1.com]] |"
"| [[https://link2.com]] |"
"| [[https://link3.com]] |"
"|-----------------------|")))
(with-temp-buffer
(org-mode)
(insert (string-join lines "\n"))
(org-element-map (org-element-parse-buffer)
'link
(lambda (link) (org-element-property :raw-link link)))))
#+end_src
#+RESULTS:
#+begin_example
("https://link1.com" "https://link2.com" "https://link3.com")
#+end_example
The following is another example.
#+begin_src elisp
(let ((lines '("#+BEGIN_QUOTE"
"[[https://link1.org]]"
"#+END_QUOTE")))
(with-temp-buffer
(org-mode)
(insert (string-join lines "\n"))
(org-element-map (org-element-parse-buffer)
'link
(lambda (link) (org-element-property :raw-link link)))))
#+end_src
#+RESULTS:
#+begin_example
("https://link1.org")
#+end_example
The following is another example.
#+begin_src elisp
(let ((lines '("This is [[https://link1.com][a link]]"
"#+BEGIN_SRC python"
"print('[[https://link2.com][a link]]')"
"#+END_SRC"
"This is [[https://link3.com][a link]]")))
(with-temp-buffer
(org-mode)
(insert (string-join lines "\n"))
(org-element-map (org-element-parse-buffer)
'link

This section show examples where =org-element-map= doesn't iterate through all links in the buffer.
The following is an example. Links in properties drawers are not considered. I expect those links to be considered.
#+begin_src elisp
(let ((lines '("* John Doe"
":PROPERTIES:"
":ONE: [[https://link1.com]]"
":TWO: [[https://link2.com]]"
":END:"
"[[https://link3.com]]")))
(with-temp-buffer
(org-mode)
(insert (string-join lines "\n"))
(org-element-map (org-element-parse-buffer)
'link
(lambda (link) (org-element-property :raw-link link)))))
#+end_src
#+RESULTS:
#+begin_example
("https://link3.com")
#+end_example
The following is another example.
The link in the =#+TITLE= line is not considered. I expect that links to be considered.
#+begin_src elisp
(let ((lines '("#+TITLE: A line with [[https://link1.com][a]] link"
""
"[[https://link2.com]]")))
(with-temp-buffer
(org-mode)
(insert (string-join lines "\n"))
(org-element-map (org-element-parse-buffer)
'link
(lambda (link) (org-element-property :raw-link link)))))
#+end_src
#+RESULTS:
#+begin_example
("https://link2.com")
#+end_example
The following is another example.
In general, links in keyword lines (i.e. those starting with =#+=) are not considered. I expect those links to be considered.
#+begin_src elisp
(let ((lines '("#+TITLE: A line with [[https://link1.com][a link]]"
"#+SUBTITLE: A line with [[https://link2.com][a link]]"
"#+AUTHOR: A line with [[https://link3.com][a link]]"
"#+SUBAUTHOR: A line with [[https://link4.com][a link]]"
""
"A simple paragraph with [[https://link5.com][a link]]")))
(with-temp-buffer
(org-mode)
(insert (string-join lines "\n"))
(org-element-map (org-element-parse-buffer)
'link
(lambda (link) (org-element-property :raw-link link)))))
#+end_src
#+RESULTS:
#+begin_example
("https://link5.com")
#+end_example
* Personal thoughts
:PROPERTIES:
:CREATED: [2021-09-24 17:41:12 -05]
:END:
I think that links in properties drawers and keyword lines should be considered by =org-element-map= because there are use cases for having links at these locations. I will mention a use case for each context
