When you set a page to be a child of another the URL of the child page becomes /parent-slug/child-slug and you can query the database for all pages that are children of a specific parent page. It helps to establish information hierarchy.
Menu order and arrangement are completely separate: you could put a link to the child page in a menu and nest the parent page under it if you wanted. That would be terrible UX, but you could do it.
To move a menu item to a child menu all you have to do is drag it to the right.
