Answer 1

@Felix
Instead of using the "&" operator, use "and"

Here is an article about the difference between the two:

Answer 2

Felix It's already like John Paul Le but you also have the flaw:

elif age >=19 & age <=64:
...
That Statement define that someone with 18 isn't a adult, just change 19 to 18. 😉

Hint: When something's inside a former if-statment you don't need to state that the next shouldn't have that values.
No Code:
If age lesser or equals 11 = Child
Else if age bellow 18 = Teen
Else if age lesser or equals 64 = Adult
