You are correct. So if you are looking at the engine, number one cylinder is the one on your left as you are looking at it. So bank 1 is on your left. If you need to change the upstream O2 sensor on bank 1, it is the one on your left, before the cats. Hope that this makes sense. Let me know if you need help, I don not mind.
