How does finishing the prescription ensure that all the bacteria is killed and that there are no surviving or remaining bacteria? Have always been told that finishing the prescription does this but never how

Actually this advice is being turned on it’s head of late. Instead of prescribing 10-14 days of antibiotics prescribers are being asked to consider 3-5 days in many cases.
You don’t need to kill every last bacterium, you can’t anyway, and just provoke resistance with long courses and more disruption to your good bacteria.
Instead a 3-5 day course in most cases will kill 95-99% of the bacteria that are harming you and your immune system can deal with the rest naturally.
