freelancing as a student

hi guys. i’m a first year uni student and i’m really looking forward to freelancing lekin fiverr upwork wagera mein kuch samajh nahi ata kya horaha hai. i’m good at content writing etc, and i’ve heard people around my age are earning a lot from freelancing so i keep wondering how to get into it. does anyone have any advice or instruction? + any other way to earn?
