This is exactly it. I definitely used a lot of walkthroughs as a kid. I also feel like games in the 90s and early 00s were just plain harder, or sometimes poorly designed.
These days I only look something up when I have got to a point of near rage over how much of my limited gaming time has been wasted, and I need to know if I am just a moron, or if it's a bug, or bad game design. Of course, then I get mad that I can't find it written out, and have to skim around in some fucking YouTube video to figure it out.
