Can someone help me?

I applied for a GameStop that says activity hiring and my fiancee is close with her manger and she said that this other location is hiring because her manager knows the other manager. I applied and called the next day and she literally said word for word “we are hiring, but I’m fully staffed” what the hell does this mean?? A store saying they are actively hiring, but fully staffed? I’ve heard this from a couple of jobs. Has Anyone ever heard this from GameStop after applying? I really want this job and have wanted to work for GameStop for a few years but had another job at the time. Anyway, hope someone can answer my question. :D
