Whatever data is displayed on the statistics page, I am absolutely sure that this gap between the numbers is connected exclusively with deleted accounts, (since the deleted accounts are currently 16,117). And the discrepancy between the numbers presented here and the numbers displayed on bpip.org is another question ... I would not be surprised if this is due to the update intervals, given that at the moment, for example, I see that btcnfan's profile has been online for a total of 23184 days.
