Child psychiatry (question about college requirements.)?

So I am thinking about going into a psychiatry field (NOT psychology)

I was doing some research and am trying to get some facts straight.

According to the article I found, this is the required education for a child psychiatrist :

Career in Child Psychiatry

Upon completion of a bachelor’s degree, usually in one of the biological sciences, psychiatrists must complete a 4 year medical program. Then, psychiatrists must complete a 4 year residency program in child psychiatry before applying for board certification in Child Psychiatry. The residency program may include such courses as inpatient and outpatient psychiatry, outpatient child, adolescent, and family treatment, and community consultation psychiatry, among other courses.

So my question focuses around schooling.

Does this mean you aren’t required to have a Ph.D or masters degree?

After a 4 year degree, you go straight to med school?

Mehhhh, can someone explain?
