Can confirm as a Chilean. Santiago gets more expensive as you approach the main part of the city (Which offers more amenities), but overall, living with 1k USD is very doable (specially with the actual conversion rate).
Living in other regions will be MUCH cheaper, but they tend to be more simple (outside the tourists hubs).
If you're not a coder, I highly recommend Flow (https://flow.microsoft.com/en-us/) Which is an automation platform designed to be used with MS office products.
There are also a lot of options in Azure , but they require a little bit more of coding (They are incredible powerful nonetheless).
The work done by them has been incredible. Their course on OO with Java was a lifesaver as a student, helping me with a lot of concepts and filling the gaps, to start working as a SE.
While I didn't have the time to complete it, their fullstack course seems also very good, has someone completed it that can share their experience?.
