Building on the previous comment. A human lifespan (in a good case) is ~ 2838240000 seconds (90 years). With a ~0.0000000000000000088162076% chance to find an address with a balance every second - in 90 years the network would have ~0.0000000250225131% chance to find a wallet with anything in it.
~0.0000000250225131% in 90 years!.
I have ~ 100% chance to not being alive in 90 years 
~0.00000142857% is the chance of being struck by lightning in any year.
So itβs ~0.00012857142% chance to be struck at least once in 90 years.
And remember - all of this is for standard 12 word wallets. To get the results for a paper wallet - take the same numbers and multiply them by infinity
