Why is page.php used to display categories instead of taxonomy-product_cat.php?

Question

WooCommerce

Good afternoon.
On my site, page.php is used instead of the taxonomy-product_cat.php template.
I can't understand why?
Here is the content of page.php.

<?php
  /**
   * The template for displaying all pages
   *
   * This is the template that displays all pages by default.
   * Please note that this is the WordPress construct of pages
   * and that other 'pages' on your WordPress site may use a
   * different template.
   *
   * @link https://developer.wordpress.org/themes/basics/template-hierarchy/
   *
   * @package benefis
   */
  
  get_header();
?>
    <script>
    jQuery(document).ready(function () {
      $('.woocommerce').removeClass();
    });
    </script>
    <div class="slider">
        <div class="slider_video_parent">
            <span></span>
            <video src="http://benefis.myihor.ru//images/video/10000000_690038651457564_3112166903667890767_n.mp4" class="videoslider" autoplay="" loop="" muted="" width="1280" height="720"></video>
        </div>
    </div>
    <div class="container">
        <div class="row">
      <?php get_sidebar(); ?>
      
      <?php while (have_posts()) :
          the_post();
          
          get_template_part('template-parts/content', 'page');
        
        endwhile; // End of the loop.
      ?>
        </div>
    </div>
<?php get_footer();

I moved the templates folder from the plugin folder to my theme.
Renamed to woocommerce.
Even query-monitor tells you which templates to use

Found the answer.
The fact is that I did not start developing this site from scratch. Before me, a miracle developer installed woocommerce and set it up, but somehow in its own way.
After reading this article https://delaemsait.info/integriruem-woocommerce-s-...
I learned that you need to include woocommerce in functions.php.

add_action('after_setup_theme', 'woocommerce_support');
  function woocommerce_support()
  {
    add_theme_support('woocommerce');
  }

It is clear that when you start developing a theme from scratch, use a template from underscores.me, do not forget to check the woocommerce checkbox when initializing the theme on this resource, then this code is inserted automatically into the functions.php file.
