No the Talmud does not say that non Jews are not human.

Infact multiple times God gets pissed off at the Jews and kills them / ruins their lives, etc.

The Bible is filled with stories of the Jewish people constantly fucking up. Its not a self flattering book at all. Countless times God calls them stubborn people.

In fact at one point, God literally gets so annoyed with them, that he says he can't even be around them even for a moment or else he'd end up killing them:

"God said to Moses, “Tell the Israelites, ‘You’re one hard-headed people. I couldn’t stand being with you for even a moment—I’d destroy you. So take off all your jewelry until I figure out what to do with you.’” So the Israelites stripped themselves of their jewelry from Mount Horeb on." (Exodus 33:5)

The Jews do not see themselves as superior to other humans. The Bible is extremely clear on this.

Edit Bonus: The reason they self isolate, is because they were instructed too, infact one of the primary reasons is that if they married the local girls in the region they were in, they'd be turned away from God and worship their local Idols. (By the way they did marry the local girls, and they did totally abandon God, and worship those idols. . .)
