At 2380 sc rank it is not impossible to get into top iits but yes it is tough as most of the top iits close at around 2000 sc rank but you just get one provided you fill appropriate choices also since you are talking about placement so I should tell you that even if you get an iit at that rank there is a huge possibility that you might have to settle for a lower branch in which placements might not be good but yes you can always do coding and get decently placed once you are in an iit.
