I don't work for moneypot so I can't say anything about how the serverseed / raw outcome is generated.
But we just tried running the around 960,000 bets on our app through a script that split the bets into 32 outcome ranges and they are very evenly distributed.
No group varied by more than 1.87% from the mathmatical average which is as expected from a relatively small data set.

Script result:
