To summarize: Did you really lost 13 BTC from deposits or was 13 BTC the amount of bets you placed?
If you deposit 1 BTC and make 13 wagers, then you did not lost 13 BTC
Or play with 1 BTC and make it to 13 and then lost the 13 BTC is also another story.
I can assue you the totals I have posted are losses in the casino after the permanent self casino ban, not total wagers.
Here are my total wagers, I know the difference ...
