These are compressed sizes, the way a site ships. They count the code each module loads up front; heavier parts, such as 3D rendering, load only when a page asks for them and are not included, and a page's own text, fonts and pictures come on top. A page loads only the modules it uses. Calls the engine entry makes to a server: 0, so a page that uses only the entry runs from plain files.
