Have you applied? Did you get a different automatic response because I also got what the other person got automatically when I submitted my app... didn't think it was a rejection just a badly phrased email but now also stressing if it was a rejectionPHurst applications are not reviewed on a rolling basis. I would email back about that, 99% sure that's a glitch. Likely when they say if you have not heard back 'then', they have missed out saying 'by then' and a related date.
Unless you missed the deadline yet were still allowed to submit for some reason. Alternatively, it is possible your application was automatically screened out due to failing to meet the benchmark exam results (A levels, GCSEs, degree...?)
