I believe so, or they could be for Eshop in general. Ashley has worked for a few people now, WarioWare Inc, Dimond Software and now Lawsons! Heck, and she even runs her own mask business.
And here people ask how she pays the bills. In fact, it is implied she's also a movie star in WarioWare itself, and Mario and Luigi series featured WarioWare as a movie. It fits with Mr.Creator of Mario himself see's Mario and friends as actors, and maybe this goes beyond the normal Mario universe into the extended Mario-verse.
But then again, there are some plotholes in such a theory it isn't worth overthinking about. Ashley works just as hard as Mona, having to work at several places, go to some sort of school and make room to perfect her spells every single day.
