What percentage of 74-year-olds survive a COVID-19 diagnosis?

This will necessarily be a very broad generalization. 

All else being equal, in the US, since the start of the pandemic, of all people ages 70-79 who have tested positive for COVID-19, about 8% die before recovering. In other words, 92% survive. 

There are many more variables than just age. Men with the virus are more likely to die of it than women are. Underlying conditions such as diabetes, heart failure, and obesity are linked to worse survival rates. Survival is better now than at the start of the pandemic because we have learned some treatments that are effective, and some other things that we should avoid doing. 

Also, the above percentage only refers to deaths. There are other possible long-term effects. Even a relatively mild case can cause permanent damage to the heart, lungs, and blood vessels. The most severe cases can leave patients ventilator-dependent or with brain damage from lack of oxygen. So, "survival" may not be the best metric to pay attention to.
