When migrating a site to WordPress, old URLs should be redirected

So I've created a function that intercepts 404 and looks for a meta value that matches the number in the URL that should be redirected.

It worked like a charm until a user posted a new article and made it sticky. This query returned the sticky post and ignored the meta query

I have tried many things to correct that which did not work that way 'suppress_filters' => true

in case of emergancy 'post__not_in' => get_option( 'sticky_posts' ) did the trick, but that's not the way. (If this post I wanted was sticky, he would not find it!)

How can I then create a WP_Query that receives a post via meta-query and does not insert sticky posts?

add_action( 'template_redirect', 'wpd_do_stuff_on_404' );
function wpd_do_stuff_on_404(){
    if( is_404() ){

        $url = $_SERVER('REQUEST_URI');

        if (preg_match('//(d+)-(^/)*$/', $url, $matches) ) {
            // looks like a dc post, lets try to find a post using dc_post_id
            $dc_post_id = intval($matches(1));
            $args = array(
               'meta_query' => array(
                   array(
                       'key' => 'dc_post_id',
                       'value' => '' . $dc_post_id,
                       'compare' => '=',
                   )
               ),
               'suppress_filters' => true,
               'posts_per_page' => 1,
            );

            $q = new WP_Query($args);

            if ( $q->post_count == 1 && $q->max_num_pages == 1 ) {
                wp_redirect( get_permalink( $q->posts('0')->ID ), 301 );
                exit;
            }
        }
    }
}
