the odds of a Boltzmann brain are so minuscule

Depends on what odds you're talking about. If you're talking about the odds of a Boltzmann brain popping into existence at any particular instant, then yes, the probability is absurdly low. If you're talking about a Boltzmann brain existing at some point in the universe, then I don't think the odds are all that small. It's the latter probability that's relevant to the kinds of issues Page cares about.
