Yes, true.

The whole “OS update when I want an app update” is because of how dependencies work on Linux. A library is installed once and referenced by any app that wants to use it. This way, an update in the library benefits all apps using it, as bugs het fixed. Also less storage is used when the one library is used by many apps.

Windows programs keep their own versions of a library and hard link to that one. That makes the app more flexible. You can copy the app and it’s dependencies around and it will keep working. In this scenario multiple copies/versions of the same library can exist in the system, which takes more space.

Of course there is some nuance. Both operating systems can have/use shared or hard linked libraries, but this is the general gist of it.
