There is, as far as I know little to no scientific evidence that cloth masks are effective at reducing the spread of covid-19 This would make the who's statement factual. There's conjecture, and maybe some empirical evidence about cloth masks, but it's weak.

There is overwhelming evidence. Dozens of studies, all show significant reduction the spread of viral diseases simply by tying a folded piece of cotton over your face. And if you need to back peddle this hard, maybe you should be so quick to snark in the first place?
