How does XDR quota for data?

How does XDR allocate quotas for data? My license is 5TB and dataset management shows that I have used 3.9TB, but I log into Datalake to check if the usage is 0. What happens if 5TB is full? Does xdr_data take up 5TB? Is it possible to set a quota or retention date for it?
