you are going to see the number of sub 0.001 wallets increase to hundreds of millions.. purely due to merchants that implement 'use once' addresses.

these millions of addresses wont tell you how many people have any coin. or how many of the addresses belong to how many bitcoin merchants. thus useless trying to analyze it for any useful info/statistic

thus the topic title
"Bitcoin Distribution of Wealth Detailing the BTC Holdings of Wallet Addresses" is erroneous
