My professor recommends us making a GitHub account as soon as possible. Why should I?

It's an honest question. His reasoning was like ""in a couple of years, when you graduate and look for a job, you'll be able to show them that you used github for the past couple of years"" and I get that. But right now I'm making programs that are too simple and that are introductory. Like create an array, print only the odd numbers from an array, write Hello world in a .txt file. Scan a .txt and count the occurences of a given word, etc.

the entire (modern) programming industry uses git.

the sooner you start getting used to git, be it github, gitlab, your own repository on a pi somewhere, the better.

on top of that, during your university years you will more than likely build projects which are passable to show off, but will be left collecting dust on a USB-stick somewhere before it gets reformatted to host as storage for three three horror movies during movie night.

so all in all, there is no reason ***not to*** start with github now, and you can set projects to private should you wish, and especially getting used to the amazing features that git offers you for handling projects, especially if you have collaborative projects down the line with your course colleagues.
