I think what's really important is how a kick works ( or not ) within each track and what's the relationship between the kick, the bass line and other audio elements of your track. There's also a correlation between music genres using specific kicks, like Techno using a lot of 909 type of kicks, Hip-Hop using more 808 type of sound for example.
It comes down to pitch, length and tonality of the kick in the end, any "decent" kick preset whether it's a sample or a plug-in preset will sound good on it's own or with very few other audio elements but might sound completely wrong when adding other elements and the relationship between Kick & Bass ( especially ) is key point to get a good mix foundation. Many producers will tell you that they start with a basic kick to get things going and develop ideas but then they will replace it and make adjustments later on.
Here's another interesting course to check out IMO but again, watch this at your own pace, come back to it several times, it's part of the music production learning process, there's a lot to grab, it comes with time & practice and the parts of the puzzle will soon make sense and reveal the all picture at some point. Nothing wrong to feel overwhelmed with terminology and techniques you grab from tutorials
