My view is that you are right. But also not entirely right.
If you imagine a universe as a point, rather than an expanse, and then imagine that point in motion through a different expanse I'll call a 'probability field'... then that object tends to continue in a predictable motion through that field, much like in newton's laws. In other words, the whole giant complex universe has inertia through time, which makes events highly scripted.
There are 2 caveats to this predestination prognosis though. 1) when foreknowledge is present, it creates a sort of potential leverage point. Precognition is something outside the 'system' (in it's current momentary state). In essence precognition is a causality violation, which "within" the universe is verboten, but it's "extra-universal" in nature, so it doesn't play by the rules. If you leverage foreknowledge to alter the event sequence which the universe's inertia is heading towards (you can really only affect yourself or those you interact with, i'm not talking about some magical ability to affect outcomes, just whether or not you stand where the coffee is going to spill. Then arguably that is a form of free will above and beyond "the script". It feels exceedingly liberating, kinda euphoric, for that reason, and a bit surreal. In an infinite parallel universes model though, it presents the possibility of not being in the exact same universe you were before though. And there's the possibility that even this falls into a sort of higher-tier of scripting.
2) on a more philosophical level... what happened yesterday? I mean you, what did you do? When did you blink? What did you eat? What did you say? Do you feel you were the author of these things? I mean setting aside the idea of being in a scripted reality for a moment, did you make choices? Now, if the answer is yes (and I assume it likely is), then let me ask, can you change what you did yesterday? I'd argue that tomorrow is very very similar.
That is the duality of the thing. You will make choices tomorrow, but you already made those choices yesterday, from the perspective of 2 days from now. I'd argue that the perspective of 2 days from now is no less valid than today's, or yesterdays. That all 3 points in time may coexist, apart from your conscious sense of location in the sequence. In this perspective, I'd say "scripted yes, but you were a co-author of the script"
