Github limits on private repository?

Question

GitHub

My game on the UE4 engine already weighs 9 gigs at the start.
It lies on the git and weighs the source code of 9 gigs ...
In this regard, the question is, how much more will the git take into itself for free? The only thing I found in the docks is that for public turnips 500mb and 1 file cannot weigh more than 100mb

And I didn’t find anything on private ones. Tell me please
