I checked the first link, it’s about the common cold. They test groups with and without masks and in both groups there was one person getting ill. Conclusion: the sample size is far too small to reach any conclusion.

Also checked the second link, it says:

There is some evidence to support the wearing of masks or respirators during illness to protect others, and public health emphasis on mask wearing during illness may help to reduce influenza virus transmission.

Not very convincingly concludes the opposite of the claim.
