Yes exactly. Although I didn't buy a new guitar, but a dozen tuners. It finally clicked when I got one that was "real time" enough to see how the tuning shifts from high to low. This was before smartphones could do it.

Doesn't help that most tuners are still dog slow, none of the beginners courses properly tell you how the guitar actually works, or what a "chord" really is. They're all just "play this and don't worry about it". To be fair it does get you going.
