what’s the difference between AA and AAA and other batteries? Why do we have a bunch of different ones?

Just size of battery. Bigger batteries store more power (given the same chemistry) , though most batteries provide the same voltage (1.5v) and current (except 9 volts and 6 volt batteries).
So the application be and form factor determine the size. Like large flashlights typically use D batteries, but a watch would use a smaller battery
