Escaping HTML and attributes in arguments passed to a function

Hello,
I am confused as to whether it is necessary to escape HTML and HTML attributes in arguments passed to a function. For example, is it necessary to use esc_html() and esc_attr(), like in the code below, when the arguments relate to HTML tags and attributes? Thanks!

<?php
       $args = array(
       'theme_location' => 'mobile-nav',
       'container' => esc_html( 'nav' ),
       'container_id' => esc_attr( 'mobile-nav' ),
       'container_class' => esc_attr( 'mobile-nav' ),
       'menu_class' => esc_attr( 'header-menu' ),
       );
       wp_nav_menu( $args );
  ?>
