No, the 737 Max has 2 AoA sensors, it just used a bizarre “only use one at a time and ignore the other” approach to (non) redundancy.
If only that was the worst design issue with the 737 Max... It is astonishing how Boeing got away with that clusterfuck of a plane. All because they didn't wan't to invent a new body and beat Airbus to market.
No, but that's fine, because Boeing needs to make money upselling carriers on redundancy.
