There are currently ~780k addresses with 1 BTC or greater (Source: Glassnode)
The world population is ~ 7.8 billion.
So there is 1 address with 1 BTC or more for every 10,000 people. Even assuming individuals with multiple addresses with fractions of a BTC, it’s unlikely that the average person will ever know someone with the private keys to 1 BTC or greater.
Bitcoin is incredibly scarce.
