Honest question, do those percentages add up?

Ex: You're 35, but you have asthma and high blood pressure.

Does that mean your mortality rate is 12.7%?

Also, your list says: > no pre-existing conditions 0.9% and > 10-19 years old 0.2% Does that mean a teenager with no pre-existing conditions has 1.1% mortality rate, or is it just 0.9%, or just 0.2%?

I'm honestly asking cause I know nothing about disease or mortality rates.
