Displaying a single result out of three results
you can do it without preprocess, by using the Twig Tweak module, it gives you the possibility to render your view in twig with display filters and so on like the following:
{{ drupal_view_result('latest_products', 'block_1') }}

The drupal_view_result give you the array of result so you can get the first result with:
{{ drupal_view_result('latest_products', 'block_1')[0] }}

of type ResultRow and then get the entity with:
{{ drupal_view_result('latest_products', 'block_1')[0]._entity }}
