I have set users to only see their own posts. But the total number of articles is still visible. Can we limit it to its own number of articles? How can it be done without plugins? related picture here:

I restricted the users to their own posts with the code below. But as the picture above shows, although the publication is one, the number of publications seems to be four. How can I make the number of publications?

function posts_for_current_author($query) {
    global $pagenow;
 
    if( 'edit.php' != $pagenow || !$query->is_admin )
        return $query;
 
    if( !current_user_can( 'edit_others_posts' ) ) {
        global $user_ID;
        $query->set('author', $user_ID );
    }
    return $query;
}
add_filter('pre_get_posts', 'posts_for_current_author');
