Of course you can lose weight by playing ball alone. If you want to lose weight completely, I suggest you run the basket. Partial weight loss depends on the part of the movement. Where you feel tired, you exercise your muscles and burn fat at the same time. If you often run to the basket, you will not feel bored at first, but also exercise your dribbling ability. Some people will feel bored and can't insist on running alone. Forgot to adopt.
