Less couched in Solana jargon

Property Processed Confirmed Finalized
Received block x x x
Block on majority fork x x x
Block contains target tx x x x
66%+ stake voted on block x x
31+ confirmed blocks built atop block x
3
0

From here

'processed': Query the most recent block which has reached 1 confirmation by the connected node

'confirmed': Query the most recent block which has reached 1 confirmation by the cluster

'finalized': Query the most recent block which has been finalized by the cluster
