Long time since I've changed the oil, but I thought the stock drain plug had a white nylon gasket that was "attached", and did not typically require replacement. Memory is not what it used to be, though.
Should not be a critical issue.
Actually found an old photo of the factory plug. It has been drilled and tapped to add an oil temperature sensor, but it's the same plug that came on the car when I bought it new in 1994.
Don't know about the other drain plug gaskets, but, the third one is called a "Seal-Tight" washer, and ..... it also works on the cross over coolant lines on the back of our cylinder heads too!
