I don't think 100 years is a requirement for a True Alpha. I think it's just used as an indication that it's a rare thing. Which it is. Bloodthirst is common amongst new werewolves, and they're in a war with hunters. One mistake (that doesn't even result in death) would make sure that very few would be able to last long enough to become a true alpha. But in beacon hills, they have a group of supernaturals (and a banshee, I say while rolling my eyes), and humans that hasn't happened before, and they have a leader (Scott) who inspires actions in people that increase the chances of a Ture Alpha happening.

Consider this, there are no other known true alphas alive, and werwolves live long enough to see at least 2. I'm fairly ertain that, given the character it takes to become a true alpha, that very few true alphas in the past made a beta, and the ones who did died at the betas hands enough times for it to be known that that's the only way to get a True Alpha's spark. Scott has enough luck, protection, and slowmo closeups to characters coming to realizations that the dialogue already let the audience know about, that he's feasibly survived long enough to inspire another True Alpha.
