People have gone over this time and time again. It's about risk reduction.
If you're working on a Covid ward with significant daily exposure, then you need to be fit-tested for a n95 mask (Which stops the virus).
The masks in your picture GREATLY REDUCE THE RISK of catching the virus when out in public. Even though they're not 100% effective, they still prevent a huge amount of infections, which is why it's important to wear one.
I hope this helps :)
