From what i understand, the virus is only transmissible through the respiratory system, thats why you can eat food that has been prepared by someone with covid and the only way you'd get it is if you somehow stuffed it up your nose or breathed it in.
Masks help reduce the spread of covid by limiting the particles that are released into the open air, however they don't do much of anything to stop one from breathing in Covid once its already in the air if all you are wearing is a regular mask, N95 respirators however filter out 95% of airborne particles including respiratory droplets (from sneezing and coughing) as well as aerosolized droplets.
To say masks are useless is misleading, but if one person with covid is sneezing and doesn't have a regular mask, everyone might get it from that guy even if they are wearing one.
