ELI5: How do dryer sheets remove wrinkles and/or reduce static if it's just the small sheet? Wouldn't it not be touching all the clothes in the load?

Dryer sheets are fabric squares soaked in fabric softener (either quaternary ammonium salts or silicone oil).
 As the dryer blows hot air through all the clothes and mixes them around, the fabric softener very lightly coats all of the load. This thin coating of softener gives the laundry the nice scent and the positively charged chemicals (cations) help equalize the electrons building up from all the clothing rubbing against each other.
