These two terminology confused me a lot when I was learning statistics.
It seems that they are totally different two things to me. A random sample is to randomly take a sample from a population, and a random variable is like a function that maps the set of all possible outcomes of an experiment.

The current only existing answer doesn't really give a general and intuitive overview of the difference between the r.v. and a sample and how the concept of an r.v. comes into play when sampling (which is what I want to read about!!!)
I will use my reduced reputation to downvote poor answers like those.
@nbro, please ask those on the main site. There we have better facilities for asking & answering questions (eg, the formatting options will work), & the information will be available for future seekers w/ the same question. Those aren't chat items.
Chit-chat is for for gossip, grumbles, & random musings that no one wants to read on the main site.
Regarding the Q whose answer you are unsatisfied with, you could ask a new question. That answer looks good to me. It has received several upvotes, & no downvotes before you, & was accepted by the OP. That stands as prima facie evidence that the OP found the information they were after.
In your followup Q, link to that one & state what you learned there & what you still need to know. Eg, you could say that you want an intuitive account that doesn't use math. The point is that it would be your question seeking what you want. It isn't an answerers fault if they provided the information the OP was after but not the information some other reader was after years later.
@gung Yes, you're right regarding "It isn't an answerers fault if they provided the information the OP was after but not the information some other reader was after years later.".
Anyway, I've already asked a question on the main site.
I have an (intuitive) understanding of what a random variable and a sample are. However, I am not sure how a random variable is related to a sample.
Suppose we have a population of people. Sampling from that population means to take a subset (which we call "sample") of those people.
What can ...
@nbro, thank you for that. It's a good question (+1). You've already got a couple answers. You might make more explicit that you want answers without math, if that's the motivation here. If you don't get an answer that you are satisfied with, you can add an edit to clarify the distinction between what you are getting & what you want. I could also put a bounty on it for you after a few days, although it doesn't look like it's lacking for attention right now.
