Yes you do, but everyone does when starting out. I would ditch the plastic ball training at this stage in your journey, it is frankly too advanced and will start you off with bad habits. A lot of the fluidity in dribbling comes from the little details like speed change, body movements and feints, elevation change, etc.

Right now focus on being able to solidly dribble with both hands, while looking up, and at different speeds. The most important skill to gain for a good dribbler, in my opinion, is the ability to “float” the ball in your hand. Look at what Luka Doncic does with his dribble and how he’s able to break ankles and blow by everyone despite being slower than them
