This is unfortunately just not correct in real life. It’s a good representation of general behavior/trends, but for instance Smallpox was around since at least 500 BC, and still had a 35% fatality rate until it was eradicated in the 70s.

The more times you roll the dice, the more often you’ll get that magic combo of lethal and highly transmissible. For the most part it doesn’t favor it, but that just makes it an outlier when it does, not impossible.
