Our current best understanding of the archaeological, linguistic, and genetic evidence (and the genetic evidence in particular became available only in the past 20 years or so), suggests that the archeological culture we label the Sintashta (https://en.wikipedia.org/wiki/Sintashta_culture), who flourished on the central Asian steppes c. 2000 BC, almost certainly spoke the language we reconstruct as Proto-Indo-Iranian (that is, the descendant of Proto-Indo-European ancestral to the modern Indian and Persian languages), likely used the term "Arya" as some kind of self-designation - and when their ethno-linguistic descents showed up on the Indian subcontinent in the mid-2nd-millennium BC, this probably mostly felt like a violent invasion from the perspective of the non-Indo-European-speaking peoples already inhabiting the region.
In other words, pretty much every modern Indian or Iranian person is in fact a descendant of an ancient people we can reasonably call the Aryans even if "Sintashta culture" is a more precise archaeological term; and this is the case regardless of what Adolf Hitler thought about how this applied to ethnic Germans in his day.
