Why do all my controllers drift only to the left

Unfortunately this has been a common issue for joysticks since they were first introduced in controllers. The PS5 controller uses the same old potentiometer joystick as prior generations, which wears out quickly and can get dust in the sensor, which causes the drift you are seeing. The only way to fix it permanently is to find a joystick that doesn’t use potentiometers to detect your input. I would check out the King Kong Pro 2, which uses a electromagnetic joystick.
