Right. As a thought experiment, assuming a 75 year lifespan, what if air pollution causes EVERYBODY to die one day earlier than they would have otherwise? Is the death rate 100%? Or is it .00365% (1 / (75 * 365))? But an age-adjusted metric can give non-intuitive results. Thanos' snap, randomly killing 50% of everybody, would have had a 25% lives-lost-equivalent. How you calculate death rate has real consequences in how you evaluate something like Covid.
