If you are not from an IT background then it would be a little tough for you to move into the DevOps field. But, if you start learning basics with all your dedication, it is not impossible either as a lot of people are moving into DevOps from a non-IT background.
Here are some prerequisites that you can start grasping before you make a switch:
Basic understanding of Linux.Unix system
Knowledge of a scripting language
Knowledge of cloud systems
Basics of Web Servers including Apache, PM2, etc
Basics of Databased like MySQL, MongoDB, etc
These are some skills that you can start with and then if you feel you are doing good, you can start diving deep into it.
