You are confusing loanwords with actual linguistic relationships. I understand Kannada fluently and it's quite plausible that the commonalities with Sanskrit are loanwords compared to more structural or fundamental similarities between Sanskrit and Persian, Latin, etc. Consider the basic articles (I, you, etc.) or many fundamental verbs, for instance, which at least modern Kannada almost surely does not share. https://en.wikipedia.org/wiki/Indo-European_copula https://en.wikipedia.org/wiki/Indo-European_copula
