> Why don't they just use those people to adjust their odds faster for everybody else ?

Volumes are not huge like in finance, you will lose more on the bet that you will make back in your marginally improved odds.

> I guess they try to cream the most addicted people, seems quite intuitive to me.

The professionals, not the addicted. The addicted expire quickly and they typically don't use exchanges anyway.

It can't be 28% for the whole state, that would mean a third of the population are degenerate gamblers.

I worked at a quant sports betting trading company, on occasion it would send the employees to place annonymous few grand bets at physical shops because it's such a problem getting people to continue accepting your bets if you are any good.

And found out that the more you bet, the more percentage commission you pay to exchanges like Betfair, which is quite contraintuitive - commission goes up with volume, not down.

I also learned a few tricks of the industry - when you open an online account they look up your address on Google Maps to see what kind of place you live in.
