That person who sent the video I think misunderstood the post, but they make a good point. Play and enjoy what you are doing but I do agree down the line to look into Talkingbass with Mark starter theory lessons, starter counting rhythms or something like a Hal Leonard theory book or lessons. Even with tabs I recommend you learn some basic counting of notes and time signature even with tabs, Songster and Ultimate guitar "pro" section has the rhythm with it, you can bypass pro kind of there's a non-paid section but you can't play the song live.
For this song however the second fret of E you can not play anywhere else fretted unless you have a five string or tune down. Sorry if I am confusing you, but it's a great and fun journey and IMO learning some theory can and will put you many years ahead of other bassist since you can jam or improv much easier, it can be simple things like a root name chug to a chord change.
Anyway good luck playing, have a great day!
