It'd be nice if more reporting on the subject highlighted the absurdity of DFS being legal but betting on game outcomes illegal. I think that DFS should be legal but at least the NY AG is being consistent in enforcement.
Nevertheless, given the number of players that draft kings and fan duel have acquired through their indefatigable marketing campaigns, I would submit that a not insignificant portion (if not a majority) of that one percent figure out the bets others wouldn't make all on their own.
Further, math and computers can most certainly help with this given that all the relevant data is public.
How long 'til this goes the way of HFT in the stock market?
