Planning to Study Data Science/Business in Germany — Is the Job Situation Really That Bad?

Hello!

I am a student from India (Kerela) who is looking into studying in Germany. That part, applying to the University and all is not a problem. However, I have heard from my friends that the job situation is very unstable, and that it wouldn't be smart to go. I want to study either data science or business management (or similar business bachelors), but have heard that both finding a job during and after that is absolutely impossible for immigrants like me, and that I'd struggle to pay my rent. I would love to hear some honest advice on how I should look at the situation in Germany, and whether or not it is even practically possible for me to study there, if the job situation really is like that.

Thank you in advance.
