Why does changing the theme change the whole look of the site?
Because the theme files like header.php, style.css, and footer.php define the layout and styles, as shown in steps 2, 3, and 5 of the execution_table.
Does the theme change the content of the site?
No, the content comes from the database and is inserted into the theme layout (step 4). The theme only controls how it looks.

Full Transcript
When a user visits a WordPress site, WordPress loads the theme files such as header.php, style.css, and footer.php. These files define the page's layout and styles, controlling how the site looks. The content is loaded from the database and inserted into the theme's layout. The browser then renders the fully styled page. Changing the theme changes these files, so the site's presentation changes, but the content remains the same.
