It is complicated. India has at least four language families - Indo-European, Dravidian, Austroasiatic and Sino-Tibetan. So Hindi (I-E) is closer related to English or Greek than to Tamil (Dra), Santali (AA) or Zeme (S-T). While it is rare for people to speak languages belonging to all four families, I know at least three people who can passably speak six languages from two or three families.
Not to take away from this but often these 4 are very similar languages that could be easily interpreted as dialects if not the identity politics.
Well most indian languages are not even mutually intelligible so idk if its about identity politics or what not !
