I "found" a wallet with Metamask. HOW??

I created a new wallet a few minutes ago using MetaMask and moved some USDT and ETH into it then did some test transactions with Sushi Swap then went to Etherscan to see the transactions. I was amazed to find out that there is a Ropsten wallet created with the same address

Mainnet:

https://etherscan.io/address/0x6f0b81E23e5a3f289aBa155F07a2761AD82Da9A0

Ropsten:

https://ropsten.etherscan.io/address/0x6f0b81E23e5a3f289aBa155F07a2761AD82Da9A0

How is this possible? Did I just blow my lottery chance?

Needless to say I created a new wallet and moved everything out...
