No that is the amount won and not the amount wagered.
That is the wagered amount i guess. Even though it's not then lets take an example
1st Bet Amount wagered 1 btc = Loss
2nd Bet Amount wagered 1 btc = Win 2 btc
So even in this case showing the amount wagered which is (1+1) btc is equal to showing the amount won which is 2 btc
