Your little finger and your thumb are shorter than your other fingers. That makes them less suitable for playing black keys. Because you can't reach them easily.

Sometimes there is no other option, and you still have to play with a thumb or little finger on a black key. Then try to play a little bit between the black keys with your other fingers. Though that's not easy either. Always use the fingering that suits you best, and stick to that fingering. It often turns out that it isn't too bad after all!
