I know this may be a very general question, but there are so many resources I don't know where to start.

I'm afraid with the free TryHackMe plan I'm limiting myself a lot.

I know portswigger trining, is it better than TryHackMe?

Am I better off starting directly with CTFs? If yes, which is the best to use? (overthewire, hackthebox ...)

Is roadmap.sh reliable?

How important are the certificates? I am a tech illiterate but never cared about certificates.

Or as a last resort, is it better to start directly with hackthebox?
