Are there people who are physically unable to do the splits?

I’m wondering if everyone can stretch to achieve splits or if there are people who have an anatomy that prevents ever doing a split?

I myself have been stretching for years at this point with an instructor but was never able to achieve any type of split, instead i got persistent pain and was diagnosed with osteoarthritis/cartilage injury at the ripe old age of 19, and the doctor said it was most likely due to stretching for the splits. How common is this? anyone else with a similar experience?
