True. Maybe 0.001%

That reply by Golfing Eagle is NOT correct. He made up a number to fit his personal opinion of this pandemic and how it should be managed. The degree of protection provided to the mask wearer is not known and making up an extremely low number is a bald faced attempt to manipulate the reader by a retired physician who should know better. Instead the comment might say the amount of protection is unknown.
Golfing eagle also attempts to slam the reports from the CDC saying this:

He, I would think, knows better. Why is CDC in quotes? He knows how to find CDC reports. Here is what is on the CDC website regarding the issue of masks and protection for the wearer:

Scientific Brief: Community Use of Cloth Masks to Control the Spread of SARS-CoV-2
Updated Nov. 20, 2020
..Filtration for Personal Protection
Studies demonstrate that cloth mask materials can also reduce wearers’ exposure to infectious droplets through filtration, including filtration of fine droplets and particles less than 10 microns...
A retrospective case-control study from Thailand documented that, among more than 1,000 persons interviewed as part of contact tracing investigations, those who reported having always worn a mask during high-risk exposures experienced a greater than 70% reduced risk of acquiring infection compared with persons who did not wear masks under these circumstances..
Conclusions
Experimental and epidemiological data support community masking to reduce the spread of SARS-CoV-2. The prevention benefit of masking is derived from the combination of source control and personal protection for the mask wearer. The relationship between source control and personal protection is likely complementary and possibly synergistic, so that individual benefit increases with increasing community mask use. Further research is needed to expand the evidence base for the protective effect of cloth masks

The circumstances of the report from Thailand are not similar to everyday use in a community. So do not expect 70% benefit to yourself from mask wearing. Nowhere is a number given and making up a number is irresponsible. CDC reports on their website represent official consensus statements of the CDC. And the CDC is clearly saying that there is enough real benefit of mask wearing for the wearer that they devote a section of their report and much of their conclusion to discussing that benefit.
