No, it doesn't, it means late teens or early twenties, hence the "twe" for twenties. You've gotten incorrect information, probably from the top of google, which is wrong often. The "twe" in tween makes no sense for a pre-teen, it is the beginning part of twenty.
Carry onward!
Not that it really matters but tween is generally meant to be between 10-12, just before 13.
