My SO said the above statement and gave me an explanation “Cold is the absence of heat or energy”, it does make sense however in my head it is like saying (in very simplistic terms) “the countryside is the absence of a city” and that is just a ridiculous statement.

In a way, there is no such thing as cold. Cold itself is not an energy or a force. Cold is the absence of heat. The reason people use this expression is to remind people what hot and cold actually are. Temperature is basically movement; it is kinetic energy of the molecules. More movement equals more heat. There isn’t a negative type of movement where things get colder if they move more. It’s a single function.
“The countryside is the absence of a city” is not an equivalent statement. For example, the surface of the sun has no cities, but you would not call it the countryside.
