Then don't look at percentages because they are misleading, there are 677288 addresses with a balance of over 1 BTC, and lower than 10 there are at least other 350k BTC in just three addresses that are cold wallets, it's highly possible to have a few tens of thousands of people with over BTC there also.
Percentages in this are misleading, I have over 1 BTC, but I also at least 7 addresses with early dust in it, I'm contributing to both numbers, the 2% over 1 and the 98% with less than that. If a shop received 50 orders and because of high fees it decided to wait a bit before batching all the coins into one new address there you have it, 50 addresses with small amounts that are inflating the numbers while representing just one user, and I could go on like this with examples like that till tomorrow.

Remember that in the end if everyone would start using bitcoins the number would be even smaller, probably gravitating towards 0.2 and then 0.02.
