Yes, but to speak in video games term, you can still move the arrow of your character. Of course your decision are the product of your previous experience + a lot of other factors. But I believe there is a random factor, when we make a decision, we do choose one over the other.

We'll never know anyway, but I feel like there would be nothing, no universe, no life, no space etc... if there was not this "random" thing.

Randomness isn't exactly how most people would define control either.

Nevertheless, I agree with your critique of determinism. Think outside the "system". Nobody knows why stuff exists or why it behaves the way it does, it's all just observation and ideas.
