Previously I had disagreed with you regarding vaccination. And this time also, I need to disagree with you.
Virus is an extremely minute organism, and even the highest quality mask may not be able to prevent it from entering your body. But that said, you need to understand how the COVID 19 virus spreads. It spreads when an infected person sneezes, or coughs. There is a study by Japanese scientists and you can refer that one:

As from this study, the virus is present in the micro-droplets which are released by an infected person. The role of the mask here is to prevent these droplets from entering the body of a healthy person. And I believe that surgical masks and N95 masks do a good job in this case.
For me, it is clear that wearing a mask can drastically reduce the chances of getting an infection. But I can agree with you if you want to say that masks doesn't guarantee 100% protection from COVID 19.
