I am a student in the same age. When I wanted to start a hobby project I looked into the AWS free tier too. It is so unclear how the end costs come together that I decided to just leave AWS alone. I rented a small cloud instance from HETZNER for ~ 3€/month and host everything myself. If I need a DBaaS I go with the MongoDB Atlas or ElephantSQL free tier. I prefer constantly paying 3€, over a free account that breaks my neck if I miss something.
