For safety reasons, you usually transfer BTC from your book to a 3rd party wallet (the fee here is often paid for by the book), before transferring again to these exchanges (you will have to pay the fee for this). The reason for this is that exchanges have been known to close accounts used for gambling purposes. Then you pay a trade fee to sell BTC to USD, and then withdraw to your bank account.
