Is it possible to analyze traffic to site sections if they are not displayed in the URL?

Question

Analytics

The site has 3 main sections:
- Relationships
- Sex
- Family
But the URL of the articles does not display which section this article belongs to. That is, all site materials have a URL like: domain/article_article_number.html (site.ru/article_1231312.html)
1) There are quite a lot of articles and they are quite old, it is highly undesirable to change their addresses. Is it possible to somehow analyze the statistics of a particular section of the site (attendance, views and other metrics) with the help of Analytics or Yandex Metrics with this URL construction.
2) Or does Analytics and Metrica rely only on the URL and for this possibility it is necessary to bring the URL into the form of the type: site.ru/sex/article_1231312.html?
