Payout question

I am using us1-zcash.flypool.org:3333 server. I receive my Zcash address from wallet-zcash.com
When I check the status of my address, I see the following:

Summary confirmed
Total Received
1.89510128 ZEC
Total Sent
1.88990191 ZEC
Final Balance
0.00519937 ZEC

Please help me understand these numbers. Is the number of Zecs received the ones that I mined ? and the one sent should be in my wallet?

Thanks.
