I'm only half agreeing with you. Yes, improvements in medicine before 1920 were dramatic. Antibiotics and vaccines work wonders, making once-deadly diseases benign (e.g. pneumonia) or eradicated (e.g. smallpox). But more recent improvements in healtcare aren't just trivial stuff either. The five-year survival rates for childhood leukemia, for instance, have been on a steady increase from 40% to 80% since 1970. Recent monoclonal antibody therapies against inflammation/autoimmune diseases have provided actually revolutionary changes in the health situation of many. Going from chronic pain and having a hard time functioning at school/work, to living a relatively normal life, is a huge thing. But it's not captured by life expectancies.
