Step-by-step explanation:
yes, you are correct in both cases.
this is in one hand exactly the definition of science (science tries to find out how the natural world works and hence how we can use that in our favor), and on the other hand exactly the problem when dealing not just with general behavior but exact results in natural systems.
mother nature "hates" exact results. it works by chance and by the law of big numbers and tendencies (only with many, many comparable events can you see a tendency of the system). when you observe the behavior of one horse in a situation, you still know nothing about how horses behave. only after observing many horses in the same situation can you see a pattern emerging.
flipping a coin 4 times will usually not show the expected 50/50 pattern of heads and tails. but 100 or 1000 flips will start to show the tendency. but they will still not have an exact and as such repeatable result and will almost never produce the limit of the tendency of a 50/50 split of results.
