Yup. Each number also has six lines between them. There's usually only four lines from what I've seen. One line = ⅕ ml, or 200 μL. Some thinner syringes will have markings for 0.5, 1, 1.5, 2, 2.5 ml. Those have one line for each ⅒ ml, but still only four lines between the numbered markers.

I feel like maybe this generated image was influenced by an image of a syringe with the half-ml markings, like in the picture below. Then there would be two markings starting with 1, and with 2, and so on. But the generation missed the ".5" part. 😅
