They are from two very different language families. Russian is a Slavic language and Slavic languages are Indo-European, which makes them 'family' of Romance languages (Spanish, Italian, etc.), Germanic languages (Dutch, English, German, etc.), Scandinavian languages, but also languages like Farsi (Iranian) and Hindi. However, Hungarian is part of the Finno-Ugrian language family, together with Finnish and Estonian (and maybe a few small languages as well, I'm not sure) and this language family is not part of the larger Indo-European language family. So, in short, Russian is in a way closer to Hindi than it is to Hungarian. However, there might have been some influence of Russian on Hungarian during the Communist time, but I'm not aware of it. Also, it wouldn't surprise me if there are a few influences of Slavic languages from much longer ago, before the Austro-Hungarian empire. I hope this makes sense!
