The Delta seat assignment map shows 4 open BE seats and 5-10 coach seats. I'm guessing all the available seats SeatCounter is reporting is due to how much Delta is willing to oversell the flight.
The reason you're seeing a 9 in most of the fare buckets is that any airline won't refuse to sell you in a FB higher than the one of the lowest fare, that is to say that if there's a lot of seats to sell but most of the discount tickets are gone, you'll see Y9.... L0 U0 T0 and such.
*but* if say there's only 4 seats left, you might see Y4 B4 M4 ...L0 U0 T0.
I'm sure that made no sense when I typed it out (it did in my head because I work with it everyday), but hopefully somebody can find some better words than I did
