you can change the words in the .po language file:
app\Locale\eng\LC_MESSAGES\default.po
#: Controller/UsersController.php:422
msgid "Avatar is required" <------------- DONT CHANGE THIS
msgstr "Profile picture is required" <-------- ADD/CHANGE the words here
once you change it, clear global cache in the admin and refresh you browser
