Beginner Friendly Suggestions needed

Hello. I started working as a QA last month and saw that my colleagues are pretty great at devops too. All of them have 4-5 years of experience while I am fully fresh out of university.

Now I want to learn about devops just so when discussion comes up, I know what's being discussed and take part in it.

Which things should I learn and how? Could have asked that to claude or chatgpt but wanted REAL advice from the REAL professionals.

Please suggest. TIA
