How to disable users to view Other pages

Question

I have a membership website where my users can create their own page. I use below snippets in function.php to remove the options of published, trash etc. of other users and only show "mine".

/**
 * Remove the 'all', 'publish', 'future', 'sticky', 'draft', 'pending', 'trash' 
 * views for non-admins
 */
add_filter( 'views_edit-page', function( $views )
{
    if( current_user_can( 'manage_options' ) )
        return $views;

    $remove_views = [ 'all','publish','future','sticky','draft','pending','trash' ];

    foreach( (array) $remove_views as $view )
    {
        if( isset( $views[$view] ) )
            unset( $views[$view] );
    }
    return $views;
} );

It is working fine. When a user create a page, it is showing only the "mine" option.

But When a new user 1st time come to create a page (they have not created any page); they still can view the "All" options where all the published page (of other users) are shown. Also when they delete his all "mine" pages, they can view the "All" option.

So how to stop users to see the "all" option when they 1st time come to create a page or delete all their pages?

<?php
add_filter('pre_get_posts', 'my_current_author_posts');

function my_current_author_posts( $query )
{
    global $pagenow;

    // Check if you are on the right Admin page, do nothing if not
    if( 'edit.php' != $pagenow || ! isset( $_GET['post_type'] ) || 'page' != $_GET['post_type'] || ! is_admin() ) {
        return;
    }

    // get current user Object
    $current_user = wp_get_current_user();

    // check user capabilities
    if( ! current_user_can( 'edit_others_pages' ) ) {

        // remove views for pages, see the function below
        add_action( 'views_edit-page', 'my_remove_views' );

        // set WP_Query 'Author' parameter
        $query->set( 'author', $current_user->ID );
    }

    return $query;
}

// function to remove views
function my_remove_views( $views )
{

    $views_to_remove = array(
        'all',
        'publish',
        'future',
        'sticky',
        'draft',
        'pending',
        'trash',
    );

    foreach ( $views_to_remove as $view_to_remove ) {
        unset( $views[$view_to_remove] );
    }

    return $views;
}
