Module installation included modules

Hello. Why are modules with metadata 1.1 in the folder of modules when downloading? the only difference between these modules and a new module is that the new has no information in the database, right?

those modules are installed by composer during the "composer create project " command.
If you are using the prebuilt/precompiled archive for installation without composer, you are basically getting just the result of “composer create project …” command on a linux server.
