because a long term span will also eventually include a period of time where it comes 19 heads in a row.

But why? Why will a long term period of time eventually include 19 heads in a row. How do you know this? You are predicting future results.... Based on past events!

No he's basing them on probability. Given enough trials, there comes a point where even a rare event becomes more likely than not to occur: over an infinite amount of time, the P of an event must be 0 or 1. That's this is based on, not past events.

We are saying the same thing, I agree with you 100 percent. Now extrapolate what you just said a little further. If over an infinite amount of time a rare event is more likely to occur, than over a finite amount of time it is as well, just less so than over the infinite.
