Special forces and special operations are (incorrectly) interchangeable for probably 99% of the population. I wouldn't chalk it up to anything more than that.
The Google AI overview did a great job: In the U.S. military, Special Forces (SF) refers specifically to the Army Green Berets, while Special Operations Forces (SOF) is the broad umbrella term for all elite units under USSOCOM, including Navy SEALs, Rangers, and Air Force Special Tactics. Simply put: All Special Forces are Special Operations, but not all Special Operations are Special Forces
