There may be some confounders that were not taken into account in that mask study. First one is it's all based on asking people about their mask-wearing habits. The other is that people using N95s are probably a lot more careful than people wearing cloth masks, and certainly a lot more careful than people who do not wear any mask. So the numbers probably are not just for the masks. But they do reflect the total picture of being careful versus being reckless.

So it would be better to say you can lower your odds of catching the virus by being careful, which includes wearing high-quality masks in indoor public spaces.
