The XBO must be overtracked in the UK by AT LEAST 30k.
Here's the (so far) combined Nov and Dec numbers according to VGC:
XBO: 494704
PS4: 468592
Now, goven that the PS4 is ~1 million overtracked, I think it's safe to assume that it is overtracked in the UK as well. That means that the XBO is even more overtracked in the UK.
