I don’t get it. How is cold, even freezing air turned into heat? How is it less energy consuming than other heating systems?

Basic answer
A Heat Pump is an air conditioner running backwards.
AC = make refrigerant super cold so heat in house is absorbed into it, super heat it so that the refrigerant is much hotter than the outside air, the heat is now absorbed into the outside air and blown away
in Heat mode = Make refrigerant much colder than the OUTSIDE air, so the heat from the outside air (yes, even if it’s cold outside, there’s still heat energy) is absorbed into the refrigerant lines, super heat it so that the refrigerant is much hotter than the inside air, the heat is now absorbed into the INSIDE air and blown throughout the house
There is a threshold below which this becomes less efficient as there is less heat to keep up with that demand which is why most systems will have a secondary heat source.
Unless you have geothermal in which case substitute the ground deep below for the outdoor air, where it’s much more stable and consistent year round.
