That's not a wallet, it's a Bitcoin address. If you're looking for a scammer who tells you he sells a wallet with the private key to this address, you'll probably find someone. But that is indeed a scammer, and the wallet is fake.
So whatever you're looking for, you're not going to find someone who gives you a wallet with 3 billion dollars, no matter how much money you pay to the scammer.
How did you find out what the question was?
Anyway, it's very fun that you even had to say that nobody will give OP a wallet with 3 billion dollars. I thought they would, but now that you clarified it, I will be more hesitant.
