Why can some (US) outlets fit a plug from either way you put it in, but some plugs have a fatter and skinnier prong?

From my non-expert understanding is that the more universal style are unpolarized, where as the design that has the mismatch prongs are polarized
Electricity flows from the positive side of the plug, through the device and out the negative. Some devices don’t care which side goes in the positive side or the negative so both prongs are the same. When it does matter they make them different sizes like that so you can only plug them in one way.
