TrackerControl data usage info

If I go to Android's TrackeControl app info, then data usage, the OS report nearly 700 MB of data downloaded in 2 weeks.
As far as I understand TC use an internal blacklist that must be downloaded, plus my personal blacklist that I update manually evey 2 weeks (energized block basic ~10 MB).
TrackerControl is always on and other apps use its VPN, nevertheless their internet data usage are stated in every app.

This amount of data seems little bit too much to me, is Android having issues recognising TC data usage or is TC really using this amount of bandwidth?

Since traffic of other apps goes through TC, other apps' traffic gets attributed to TC.

This is a part of Android, and I can't do anything about it.
