ORDER BY

Modifying the query so we add 'and profile_id sent a message'

I am not looking for profile_id where only staff3 sent a message
(there is no example of this with my inserts)

I do not understand this question. I think you might have added "not" incorrectly, so I am assuming you want the opposite of the previous question:

SELECT
        profile_id
FROM a_messages2
GROUP BY
        profile_id
HAVING sum(CASE WHEN sender <> 'staff3' THEN 1 ELSE 0 END) = 0
ORDER BY
        profile_id
;
