I think it’s a touch more nuanced than that but yes the plot does follow Hari Seldon’s creation of a school of thought and study called psychohistory.
The main plot is that humanity would be plunged into 30,000 years of dark ages full of bad shit but Seldon believes following his plan it can be shortened to only 1,000 years of real bad times for the schmucks born then.
Like you said, one of the themes the books talk about is the paradox of knowing the future and if you can or can’t change it. If you know the future and do something to change it to be different from what you predicted - does that mean you did or did not actually know the future?
