Hi guys, whats the difference between Outstanding and Statement balance?

My current understanding is that Statement balance is my previous period balance
and Outstanding balance is my current period balance which is not yet due AND my previous period balance (which is statement balance)

So shouldn't my Outstanding balance ALWAYS be more than Statement balance assuming that I have not yet paid my previous AND current period balance?

Hmmm, I checked and did not receive any cash rewards / refunds.

So weird...
