Coinbase summary

I’m trying to fully understand what Coinbase is telling me with this chart below. I know the math that gives my balance of $32k is my Eth value per crypto share.
What I don’t understand is how Coinbase comes up with all the other dollar amounts.
Can anyone explain how CB gets to these numbers below!
