<?php
while(have_posts()) {
the_post();?>
<h2><a href=”<?php the_permalink()?> “><?php the_title();?></a></h2>
<?php the_content(); ?>
<hr>
<?php }
?>
What do have have\_posts() and the\_post() actually do? I get that have\_posts returns a boolean, but is the context different depending on whether The Loop is in an index, single, or page file? So for index I guess it finds the blog posts in the database, but for page the\_post will just select all the content the user inputted in the admin panel?
the\_post is essentially iterating over all the posts in database while at the same time selecting the most recent one? Is that how it works?

It works off of the global $wp_query, which is, as the name implies, an instance of wp_query:

The loop in general is explained a bit here:
