The world does have order, but that order emerges from randomness through the laws of probability.
Say you roll an ordinary die one time. The outcome is completely unpredictable -- completely random. You are as likely to have any of the faces come up as any of the others.
But say you roll the same die six million times. The outcome of that looks orderly. You will have something quite close to a million results for each face. It won't necessarily be an
exact million, but it won't be far from it.
The order we observe in nature is a product of many indeterminate events, huge numbers of them whose aggregate outcomes are no longer random.
As for people making choices, as I said above it's a question of perspective. I make choices (I know this from subjective experience). You are like me; therefore I assume that you make choices also. I'm comfortable with that assumption and it makes no sense to me to assume the contrary. But what I actually observe, as distinct from what I assume, is that your behavior is unpredictable except as a set of parameters. There is no observed difference between that and a random event.
Which leads me to my final and weird conclusion: there are no random events distinct from choices. Every choice is, from another perspective, a random event, and every random event is also a choice, made by the actor of the event. A photon chooses to be detected at point A rather than point B. Our own choices are the same process as that, except on a macroscopic level and informed by information-processing tools.
