quick question, when y'all turn on the air conditioner, the lower the temperature is, colder it'll be, so my air conditioner has warm mode, is it the same as the cold mode, or opposite? (temperature)

It is the same thing.

An air conditioner is a heat pump operating on the transfer of heat from one area to another. And what matters is what the thermostat in the room registers. If the room needs more cooling because the thermostat says so, the air conditioner will turn on and cool the room.
