Why Every Pin is Low in arduino code

Hi Sir. I found some difficulty while understanding the code of arduino. E.g When u receive forward command from python program. Then the forward pin should be HIGH. Why it is all LOW in functions. Doesn’t it that mean to off the pin. If it is LOW then how can car go forward...
You answer will be appreciated sir
