How should I go about learning league of legends?

I come from mobile legends, the ripoff mobile version of LoL but I found ML Way too easy and too many broken heroes, so I hope to move to LoL for a better challenge.

I know some of the basics (mainly lane management and staying under the turret etc, same with jungling to some extent), but I’m not sure how I should start off. What lane would teach me the most? I’d give myself a pretty low ranking in LoL
