This doesn't mean anything at all. Some big whale with 1000 btc can create 1000 individual wallets with 1 btc in each. What information would you get from this? Nothing. Even if these were all legit people holding 1 btc, that wouldn't tell you anything too.

Some exchanges/casinos also hold their coins like this. They don't hold all of their stash in one address so it won't gather attention.
