Restrict URL direct access using wp_get_referer

Hi, I want to prevent a URL from being accessed directly using wp_get_referer, and I’ve codes like below:

function registration_form(){
        if ( ! is_page('registration-page')) {
            return;
        }
        if (wp_get_referer() == (home_url('/registration-tos/'))) {
            return;
        }
        wp_redirect( '/registration-tos/' );
	}
       add_action('template_redirect', 'registration_form');

The codes work perfectly but I can’t edit the page from wp-admin, I always redirected to registration-tos page, show a change the code like below:

function registration_form(){
        if ( ! is_page('registration-page')) {
            return;
        }
        if ((wp_get_referer() == (home_url('/registration-tos/')))) || ((wp_get_referer() == (admin_url('/post.php?post=12800&action=edit')))) {
            return;
        }
        wp_redirect( '/registration-tos/' );
	}
       add_action('template_redirect', 'registration_form');

and the codes also work like a charm.
but when I change the code from (admin_url('/post.php?post=12800&action=edit'))) to only (admin_url()) the code doesn’t work.

The question is: Is it possible to add admin url to the referer list without adding full URL like this: (admin_url('/post.php?post=12800&action=edit'))), is it possible to get only admin_url()? It because I have many pages to be restricted from URL direct access, and I don’t want to put their ID’s one by one.
Or maybe there is a way to get dynamic ID’s here (admin_url('/post.php?post=12800&action=edit'))) ?

Thank you in advance.
