Some websites say that moss does have stomata, some say they don't. I'm confused. I know that the moss have no xylem or phloem or roots but what about stomata? If the moss have no stomata how does gas exchange occur through the leaves?

why do some mosses not have stomata though?

Only the moss sporophyte generation has them. So, they appear on the capsule, but not on the 'leafy' part of the plant, which is the gametophyte.
The same goes for hornworts, but not for liverworts, which completely lack stomata.

some moss sporophyte capsules do but moss gametophytes don't. Mosses don't have true leaves(which, by definition, have vascular tissue): they're only 1 to 2 cells thick and don't need stomata.

Moss sporophytes typically have stomata (stomates), pores for gas exchange (Liverworts lack them)
