I've just made opening move on 11 games,Why do I get the same opening dice rolls across multiple games?

I've noticed this before but now it's really bugging me

My opening dice for the 11 games were as follows:

3 games (5/4)
3 games (5/3)
2 games (5/2)
2 games (6/2)
1 game (6/1)

Lots of same opening dice numbers, this doesn't seem very random to me

Anyone else seeing similar or just my luck?
