There is always hope that they have a few more acceptances to send out (I myself am in a similar waiting period), but they seem to have sent out a great amount of acceptances already. Based on the results page of GC, they finished most of their acceptances the Friday before MLK day (this past Friday..) They did however issue a few more acceptances at the beginning of February before they sent out rejections. I am not sure about your LORs and SOP, but the rest of your application seems really solid and competitive.
TLDR: They are probably finished with the bulk, but there is always a chance until you receive a rejection.
