There is some karma that you might realize in this birth but as I said in the post

Karma transcends many cycles of life, it is not an instant cause and effect, but may come about from a previous lifetime.

It may come about from a previous lifetime and also your karma may not come to fruition until the next life.
That is true - the ultimate goal is to

eradicate all karma so that you don't have to return at all

Break that cycle of rebirth!
