What's the right roadmap from Zero Tech experience to Devops Expert?

What’s the right roadmap to use for an enthusiastic beginner that wants to devote to learning , using labs and the engineer in pro on a daily basis full time?.

I searched the domain based devops learning path (DevOps Roadmap & Learning Path | Kodekloud) and the role based devops engineer learning path DevOps Engineer Learning Path | Kodekloud and was suprised that the two had several differences.
Since i’m from a non I.T background starting from scratch, am i meant to combine and learn the two roadmaps?
And when picking courses from a roadmap, am i expected to practice in playgrounds and the Kodekloud engineer or just finish the whole course before brushin gon my skills?

I signed up because of the lab environments but am i expected to still run a terminal on my private computer and do each course’s stages outside of KodeKloud?

I read on some forums that it’s best to open my own accounts with all the devops programs and tools on my computer but be mindful that the cloud services will have charges when using their systems outside of your labs environment.

Apologies if the answers are obvious.

I think you are overthinking it. Just pick one of the Learning Paths and start from the beginning. You’ll work it all out on the way.
