You can randomly look at any of them and if it's got coins in it then you can do what you want with them.
Obviously, the odds of finding any are a touch remote.

I put it at 1 in 1,500,000,000,000,000,000,0000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 of getting at least 1 bitcoin with each refresh, if there was only one bitcoin per wallet. In reality, the odds would be worse than this as the number of non-empty wallet is far smaller than the 18 million bitcoin. Still, better odds than England winning the Ashes
As a side note, a lot of countries and big tech firms are sinking billions into quantum computing. China has invested 15 billion. Should one of them be successful in the next few years in making a leap forward, bitcoin, as it stands today, would become worthless as they could rip through 2^256 encryption
