Dominique, I think you’re looking at the columns ‘Income’ and ‘Payouts’, and mistaking Income as Deposits and Payouts as Withdrawals. Instead, these are wagers and winnings.
From their typical reporting page,
take Income, subtract Payouts, subtract Incentives, subtract Progressive contributions, and you’ll get the figure in “Casino Profit”.
These numbers look just as one would expect in your example.
I think they should at least rename Income, and call it Wagers.
