I was rewatching an old video on YouTube and the guy was able to walk again after 10 months of practicing yoga and losing 140 lbs. If no one on earth can exactly predict when someone will die or if they’ll be able to walk again, how and why do doctors come up with these predictions?

Let’s say you are feeling tired, do not have fever, but you are coughing and have sore throat. You decide to take some time off from school or work, until you feel better.
What would your prediction be for when you will be back? How would you make that prediction?
The answer is the same as the answer to your question: Doctors see many patients with patterns of symptoms for a set of diseases. They also observe all of these patients after treatment. They record the results, publish papers. Doctors also read studies from many other doctors and learn from their experiences.
Just like you understand the symptoms of cold well and generally estimate accurately how long it takes to feel better, the doctors understand diseases they have studied.
Just like how a cold sometimes lasts 3-4 weeks for some unknown reasons and your predictions can be wrong, doctors also can make bad predictions.
