Wordpress displaying news from different categories on different pages?

Question

WordPress

Hello! How can I extract data from the database and display it on different pages? For example, on the "Home" - news output, on the "Participants" page - display of certain articles on this topic, etc. How can this be implemented? As I understand it, either to write a plugin to learn or to perform some actions with the base, I don’t know where to dig. Please help with advice or resources or ready-made examples.
