That sort of advice from CT is for advanced lifters.
For the time being, just concentrate on the conventional/basic stuff (strength progression with decent enough total volume, and getting the bodyweight up)...I know it sounds boring (LOL) but it works.
I would recommend having 2-3 days off per week depending your recovery (over the long term, do you feel fine? Or are your lifts constantly stalling and are you feeling like a wreck despite bodyweight slowly going up and eating enough protein?).
So you could do this:
Back + Biceps / Chest + Triceps / Lower body + Delts
Wednesdays and Saturdays off
Thu: Lower body/Delts
Mon: Lower body/Delts
Ideally you would have a deadlift variation on one lower body day (good for hamstrings), and then do the squat on the other lower body day:
Lower body day 1: Stiff legged deadlifts + Leg press
Lower body day 2: Squats + Hack squats/other machine or whatever
Reason for splitting it up like that is because the biggest exercises (deadlifts/squats) are very recovery intensive/demanding and are usually best done apart from each other if your split allows it.
