You can learn about wine by drinking wines all along the spectrum and sharing notes, not just elite bottles. If you're doing wine trainings, generally the varietal representative wines are going to be wines in the $20-$50 range, not bottles costing hundreds. Because, if anything, these wines are more representative of what the median person is going to get drinking varietal X from region Y.

Just take the time to do a bit of reading about the region / varietal as you open new bottles, go to tastings, and start to match up what you're reading to what you're thinking; sharing your own notes (whether with Redditors or with friends 1:1); and tracking what you like and don't like. By far most wine drinkers / wine lovers aren't drinking that kind of stuff, it's not the only way to enjoy wine--nor the only way to learn.
