I’ve learned some basic probability theory, like random variables, pdfs, cdfs, joint pdf, renewal processes, etc.

However, I know nothing about Markov chain. I don’t even understand the definitions of ***stochastic processes*** (especially those notations). Is it simply *”**random* *events that occur one after another”*?

Can someone explain stochastic processes in plain English? Can I say it is a collection of RVs along a timeline?

Pretty much, and the variables are drawn from the same space. More generally you can think of it as a family of random variables sharing a state space and indexed by some set which is usually a subset of the real line — time being the natural interpretation for a time-dependent stochastic process.

You might get better luck asking this question in r/askscience or r/askmath. Sorry that this does not answer your question, but the people who answer questions on those subs are very smart. Nerds, even.
