Nope, not the same. Has to do with how big the "holes" are in the material on a microscopic level. Out west, the rules about what qualifies as a "mask" indoors are much clearer. Aerosols are really tiny.Do you not feel that a neck warmer pulled up over mouth and nose qualifies as a mask. It’s not as good as medical style or n95, but many people are using cloth ear loop masks. If the material is the same, don’t you yhink it’s adequate?
Cloth masks are also not as effective as a surgical mask because of the internal structure of the material. There is a reason they aren't used by healthcare professionals working in a hospital. But someone who is aware enough to wear a cloth mask consistently might also be aware enough to avoid lengthy exposure to people who are potentially infectious and don't even know it.
For anyone who wants to see a scientific comparison at the microscopic level:
Microstructure analysis and image-based modelling of face masks for COVID-19 virus protection - Communications Materials
Face masks are key for slowing the spread of COVID-19. Here, the microstructure of three common masks is determined by x-ray tomography, combined with image-based modelling of droplet permeability, revealing that N95 masks are best for droplet filtration.
