What's the deal with EM?

Hi everyone. I am a first-year med student interested in EM. I am really confused why 555 spots did not fill. Can someone please explain this in very simple terms to me, as If you were talking to a child? I don't get why those spots weren't filled if there are still people who have to SOAP for EM. Will they just apply for those spots? What does this mean for the future of EM? Should I be considering other specialties?
