This is a pretty good (and free) textbook: https://otexts.com/fpp2/
To elaborate on my point above, you can definitely get some results quickly without understanding how it all works, but even a small bit of knowledge about whatever method you're using can help dramatically when you're trying to debug things.
I don't think the book above has that much maths, and it's definitely aimed at newbies to forecasting. The examples are in R though, which may not be particularly useful for you.
A simple trick question to see if you are one: Given a dataset with significant sample imbalance, how should the optimization be adjusted to account for this?
If you want to just figure out how to call some functions and get an output from them - yes, of course you can. Do you care about getting useful results? Do you want to do this as a full time job or is it just a one-off time series problem?
There are no shortcuts with statistics. It will all seem to work out fine until you involuntary shoot yourself in the foot and you most likely will because doing forecasting properly is tricky. If you are lucky you will notice something doesn’t look right but you might not.
I heard about a program that looked great to do data science from just data a while ago, but I can't find it :/ It was on Show HN I think
I found that tho, don't know if it's gonna be helpful: https://towardsdatascience.com/top-8-no-code-machine-learnin... https://www.obviously.ai/
