Do humans really have choices?

Ever heard
"You are what you eat"
"You are known by the company you keep"

I am sure you must have.
What you eat and what company you keep depends on the fact where you were born.
If you are born in a rich family in USA, you are different. If you are born in a squatter settlement in India, you are different.

You eat different, you keep company with different. Can a poor child ever equal a rich child. No.
Can you change your family. No.
Can you change what you eat? No.

So do you really have a  choice to be whatever you want?
