Which exact files and directories have this GID and which are their UIDs?

GID 1001 is a default group for UID 1001 which is default UID for a second created user in your system. Possible explanation of the existence of this GID may be as following: in one of your systems you added a second used and created some files and directories with it. Then you reinstalled your system, backed up your files in your home directory, and GID (together with UID, possibly) of that user persisted in the ownership properties of those files.

UIDs and GIDs are stored in files' metadata in inodes, that's why it's theoretically possible to have files belonging to nonexistent users and groups if you add or remove these. So, it's up to user or administrator to keep the consistency of files' ownership in the system.
