* Athlete: Professional athletes' salaries range enormously. A rookie in a minor league sport might make minimum wage or less, while a superstar in a major league sport can earn tens or even hundreds of millions of dollars annually. The sport (e.g., basketball vs. soccer), the league (e.g., NFL vs. Arena Football), and individual performance all heavily influence salary.
* Teacher: Teacher salaries vary significantly based on location (rural vs. urban, state vs. state), experience level, education level (e.g., Master's degree), and the specific school district. Generally, teacher salaries are considered modest, especially when compared to the top earners in other professions.
* Doctor: Doctor salaries also vary widely depending on specialty (e.g., neurosurgery vs. family medicine), location, years of experience, and whether they're employed by a hospital or in private practice. Specialized surgeons and other high-demand specialists can earn very high salaries, while family doctors or those in rural areas may have lower incomes.
In short:
* Top-tier athletes massively out-earn the vast majority of teachers and doctors. The highest-paid athletes earn incomes that are orders of magnitude greater than even the highest-paid teachers or doctors.
* Many athletes (especially those in early careers or minor leagues) earn far less than the average teacher or doctor. The vast majority of athletes do not achieve superstar status and earn comparatively modest incomes.
To make a meaningful comparison, you'd need to specify the sport, league, athlete's position, teacher's location and experience, and doctor's specialty and location. Even then, the comparison would only be valid for that specific instance.
