Except that they can always get a loan to cover it from the Fed. Back in the day, it took 10% of depositors to make a run on a bank. Now it requires a large number of depositors in the same area to run on all the banks to cause an issue. The reason for this is that banks can a) lend to each other and b) borrow from the Fed banks. This means that more money is just a shipment away. And since the Fed is the government, it never runs out of money. It can just print more to cover the cost.
