UPDATE 2 Got it working. Code below:

add_action('acf/save_post', 'yl_send_booking_email_after_status_update', 5);
function yl_send_booking_email_after_status_update( $post_id ) {

    // Get submitted values.
    $values = $_POST['acf'];

    // Check if a specific value was updated.
    if( isset($_POST['acf']['field_5ed8117407663']) ) {

        $to         = $_POST['acf']['field_5ed41758ed4b5'];
        $subject    = $_POST['acf']['field_5ed81174076f2'];
        $message    = $_POST['acf']['field_5ed8117407741'];

        $headers = array
            (
            'From: ' . get_bloginfo('name') . ' <' . get_bloginfo('admin_email') . '>',
            'Bcc: ' . get_bloginfo('admin_email'),
            'X-Mailer: PHP/' . phpversion(),
            'MIME-Version: 1.0',
            'Content-type: text/html; charset=iso-8859-1'
        );
        $headers = implode( "\r\n" , $headers );

        wp_mail( $to, $subject, $message, $headers );

    }
}
