No, what you are teaching is a false claim made by certain people who want to claim they are the "missing" tribes of Israel.
There were still distinct tribes (from the north) in Israel at the time of Jesus - 700 years after the exile, which basically disproves the notion that it was only a few.
It was sufficient (a big enough remnant) for it to be continued through those centuries and including the exile to Babylon.
You also forget there was Levi and Simeon.
