Huge stumbling block and source of confusion for me. During the steep learning curve setting it up, I'd often search online for help/tutorials and they'd all reference "certbot" which I couldn't find anywhere on my system. As a newbie, I frequently said "WTF is this certbot thing, I'm using letsencrypt!" Wasn't clear at all. At some point during my system updates, /usr/bin/letsencrypt became a symbolic link to /usr/bin/certbot and it became obvious.

Sounds like you were running a distro that didn't keep its packages updated. By the time everyone was calling it 'certbot', well, it was called certbot.
