Wearing general mask provide more protection to others than wearer. It’s more effective at catching aerosol exiting your mouth and nose then preventing them from coming in. In terms of effectiveness i saw a study that put cotton 30%, blue surgery masks 60%, kn95 80%, n95 95%. So anything is better than nothing.

By far not going to work is a huge risk mitigation factor for most people (100% effective), which is why it is hard to decouple distancing from poorly worn cotton masks, which is mostly what happens here.
