I don’t understand what is different that prevents cars from starting right up in cold weather. Fuel is present, air is there..spark plugs are …sparking ..and as long as you have a strong battery the starter is turning the engine…why the struggle?

The battery has less power, AND is fighting more resistance.
1. Cold makes chemical reactions go slower. That includes batteries – which have less power as it gets colder.
2. The engine has a bunch of parts sliding through fitted openings, with a lubricant. As it gets colder, the engine block shrinks and all the fittings get tighter. At the same time cold also makes oil (the lubricant) thicker and harder to move.
