It would be really cool. We already know everything at the lowest levels is a probability cloud. There’s beauty and contentment in not really being able to nail anything down for eternity…

That's a result of the Copenhagen Interpretation. There are other interpretations of the math which don't rely on reality fundamentally being a probability cloud/wave/field.

I’m not well versed in this but if fundamental particles are probability clouds, the future is not deterministic.

Why not? Every cloud that matters is resolved. What's to say a different resolution to any cloud can be possible?
