acf/save_posts is run on any page where custom field are shown and only when there are acf fields shown and submitted.

If acf/save_post is not running then there are not acf fields being submitted.

when ACF passes the $post_id value to your filter it will be in the form

"user_{$user_id}"

in order to use standard WP function you will need to extract the user ID

function whatever_your_function_name_is($post_id) {
  // see if the post ID is for a user
  if (strpos($post_id, 'user_') !== 0) {
    // string does not start with user_
    // bail
    return;
  }
  $user_id = intval(substr($post_id, 5));
  // your code to update user here
}
