the point is that u can give vs a list of addresses with balance in them and if it finds a private key then it is one to an address with btc in it.
If you give a full address as target and let VanitySearch run for the next billion years you might be able to find a match. Too bad you won't be a life to see the result

But seriously: If you are trying this kind of tooling to get rich fast you are wasting your time!
