Alan, that is partially true, but the long term indicates what your odds are for winning for each hand played. And that's what's important. Sometimes you'll beat the odds, sometimes you will fall behind the odds, but as you play more, you will get closer and closer to the expected return.
You can't ignore the per-hand odds and say, "Well, I'll never reach the true long term, so who cares?"
That's like saying mountain climbing and spending the day at the library don't have a considerable difference in danger, as a few people have died in library fires over the years, and most people survive mountain climbing, so each instance of library visitation and mountain climbing each carry their own chance of death, and you shouldn't worry about the long-term odds of dying in either of them.
