First the blocks are "new", then they should be "imature" and on some pools you see already what you will get later, as soon they become "Mature" you will be finally credited.

Usually if you mine within a pool it's not important who finds a block as the revenue from the block is shared between all miners of that pools in respect to the shares they mined of the block (on PROP Pools, on PPLNS Pools it's a bit different but also payed per shares not special to the block finder).
