The most worthless jackpot or proof that /dev/random Is REALLY bad

I created a new wallet (using go-ethereum) to use on polygon Mumbai (testnet) and end up to have found same address (hence same private Key) on etherscan that was active 6 years ago and stop being Active 3 years ago. And also Active on binance 110 days ago… I'm still puzzled if i hit a (worthless) impossible jackpot or computer random Is weakiest than i thought. Also i notice It cause my wallet was emptied evry time (on Mumbai, so no value) by someone else (i Hope the owner of the other 2 activities on BnB and eth).
