It's like this: real masks (N95, etc.) obviously can work, while they are worn properly. However, realistically, people wear BS fabric masks, and they wear them incorrectly (over beards, or leaving gaps around the nose) Also, their kids are partying and will bring the virus home anyway. So in that sense, masks probably make little difference. Here's a meta-study: https://www.acpjournals.org/doi/full/10.7326/m20-3213 and another: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7191274/
