What will be considered duplicate pages, what to close from indexing?

Question

WordPress

Tell me please!
The wordpress site has a MAIN page on which all posts are displayed,
let's say I created the “Cars” section and the “Lada” subsection. I
posted a post about the LADA car. Now if you click on the “Main Page”, on the “Cars” section, and on the “Lada” subsection, my entry will appear everywhere.
Question:
1 Will it count as duplicates?
2 I gave a description for each heading and subheading for SEO optimization. If these are duplicates, how to close them correctly and where (in Robots.txt?)?

Answer 1

A duplicate is a page that is available at several urls, if you did everything right, you always open the same url, just from different places
