So the rewards in your wallet are from your first post, which actually had some payout. You should "claim" those rewards in your wallet. Until you claim them, they are basically just sitting there doing nothing. Once you claim them, you will see the 3.942 SBD and 0.831 SP show up.
You currently have .504 SP (Steem Power)and .001 SBD (Steem Dollars) in your wallet, those numbers will go up once you claim your reward. The "delegated" SP is a delegation from Steemit, Inc. It provides you the bandwidth necessary to transact on the Steem blockchain. Steem Power is bandwidth - every action on Steem blockchain takes a little bandwidth, every upvote, comment, resteem, etc. If you did not have that small delegation, your account would basically be worthless as you would not even have enough bandwidth to do anything :) Hope t his helps! (and you will have some more rewards once the post pays out that I upvoted a few days back). Cheers - Carl
