This is what the CDC says about the effectiveness of Universal masking as source control.....

Sorry but the CDC "science brief" is full of errors and junk observational "studies" that prove nothing. In the one RCT study cited thay really couldn't tell if any reduction was due to masks, social distancing, or handwashing. Plus they actually coached the masked villagers to social distance more during the study. Too many confounding variable to be reliable.
If you really want to understand why observational studies are junk science and why the mask mandate advocates keep using them instead of RCT studies, read this article in full.
