If you throw the ball and it goes into the basket, you have "made a basket." If you throw it second time and it goes into the same basket, you have "made two baskets." In other words, "basket" can mean "a successful shot." It is like the word "goal" in football (called "soccer" in the US). A "goal" can mean a metal frame with a net. There are only two "goals," one at each end of the field. However, a "goal" can also mean "the act of scoring, by putting a ball into the goal," and during a soccer game the teams may score more than two "goals."

Shooting a basketball into a basket is called making a basket when you throw a ball threw the hole . When you take more than one throw/shot it is called making baskets or shooting baskets or taking baskets or playing baskets.

‘Shooting baskets’ is an activity. It means playing at a basketball hoop without playing an organized game. Hey, Mom, I’m going to go shoot some baskets at the park. (I’m going to bring my ball to the basketball court at the park and play around) To be honest, the phrase ‘we used a ball to’ sounds unnatural. Maybe it’s said because it’s a show for children and they are trying to introduce simple sentences. I can’t imagine a native saying that naturally.
