cloth masks made it less likely for the person wearing them to spread COVID if they had it, by limiting how much particles they were able to put in the air from coughing or sneezing. they didn't do much to protect people from catching COVID if they breathed in particles, since the particles were small enough that they could get through the cloth masks. they were still a net benefit, more so if everyone in a setting were wearing them, even if they weren't perfect. the N95 masks and other medical grade masks are better because they made it much less likely to both spread and catch COVID.
