Yes, they're there and installed on first login. Some will auto install a bit later.
This can be proven by when you go into uninstall it look at the space used. It will be tiny.
Part of the reason those shortcuts are there are on consumer editions because a) lots of people have no clue how to do anything and need a helping hand b) the vendors pay to have that installed as marketing, which helps lower the cost of the windows license
Personally I don’t even look at the whole mess of a start menu when I’m in Windows.
I wonder if it depends on the image.
