ELI5: What's the difference between a psychologist, psychiatrist, and counselor?

I know psychiatrists can prescribe meds and counselors cant, but is there a difference otherwise?

Psychiatrist: Has a medical degree, like a doctor but has specialized in diagnosing and treating mental illness, emotional disorders and behavioural issues. They often handle prescribing medication. 

Psychologist: Has a bachelors degree, continued to graduate training in psychology and specialize in treatment and diagnosis of mental illness, emotional disorders and behavioural issues. They work with a patient on treatments but do not prescribe medications. 

Counsellors: They come from all background and may have masters or doctoral degrees from counselling programs however they may not have specific training in assessing and treating mental illness.
