Ah, yes, now that's interesting. In the UK you do not pay tax on winnings from gambling so, assuming the government gets a cut, this might be in lieu of tax that they would otherwise not accrue from the professional/expert gambler due to their winnings not being taxable. And modern KYC checks mean, I'd imagine, you can't simply subvert this by running multiple accounts or by periodically shutting down your accounts and setting up new ones.
