In general, the more wager = the more points for the airdrop but there is specific allocated points for the airdrop as far as I can see, everyday they are allocation 2M points.
There is daily threshold on how many points are available daily to claim so gamblers and participants can wager more to increase their ranks and percentage of points to claim from 2M points threshold.
If I understand it accurately, points will not simply be credit to each participant with a fix rate of conversion from wager money to point but it relates to total money wager each day. Assume I wager $100 today, I can get 1 point in the airdrop on today but tomorrow with same $100 wager, I can get 10 points if there are less wager money totally by all participants tomorrow.
