Are watermelons divided into male and female? ?

I bought a yellow-fleshed, crispy watermelon at the Erjie Farmers’ Association. The lady on site enthusiastically helped me choose the watermelons and even taught me how to tell male and female watermelons by looking at the “navel”. But in fact, there is no difference between male and female watermelons.
On the way home, the watermelon cracked due to the bumpy road, but fortunately the flesh was refreshing and delicious, suitable for people who don’t like sweet things.
