Autism is a spectrum so a lot of "symptoms" affect some people more than others. It isn't a black and white case of "autistic people lack empathy" and if you have empathy, you can't be autistic. You can have empathy, ranging from "sometimes" "a little bit" "under certain circumstances" right up to what is expected of someone neurotypical.

I have some capacity for empathy. Sometimes it does concern me if someone is upset. If someone breaks a leg or loses someone close to them, I can feel sad for them or sympathetic towards them. Other times I couldn't give a monkey's behind, or I may sympathise but not really want to hear about it. I have had only a tiny few people I've ever really had a close bond to, and those include an old man and a rabbit.
