Wearing mask might just delay getting the infection. I wore mask all the time, wfh and go out only for groceries, still got infected. And when the CM gets Covid a second time after vaccination anyone can get it even with mask or vaccination.
The point of wearing masks is mostly to prevent you from infecting others if you're already infected. They're somewhat effective at preventing infection but that's not what they're best at - if you're wearing a mask in a room with an unmasked, contagious case, you're still in danger.
And if you’ve had it or been vaccinated?
