"Corked" refers to a specific fault--the presence of trichloroanisol (TCA), a chemical that those gifted (cursed?) with the ability to taste it can detect in miniscule parts-per-trillion concentrations. Yet there are others who can't taste it at all.
The TCA taint has been described mainly by smell. It has the aroma of wet cardboard, or a musty basement, or a toilet bowl. A similar sort of musty taste pervades the wine, as well, usually obscuring almost any other sensory qualities. All too many's the time I brought up a bottle from my cellar, opened it, took a first taste, exclaimed, "Oh, no! Not again!', grabbed a second bottle, opened it, tasted it, and breathed a sigh of relief that it, too, wasn't tainted.
As a newbie, IMO it would be worthwhile to intentionally seek out a corked wine to taste, just so that you know what the characteristic is so you will recognize it again when you encounter it.
I can't say whether or not the wines you cite were corked, but it definitely sounds plausible, especially since you've had other wines of the same time (and I assume the same vintage?) that were OK.
Bad storage causes other faults. For example, a wine being "cooked" due to exposure to high temperature. This tends to give the wine that might taste, say, of black cherries and plums, instead the taste of raisins and stewed prunes. It's hard to describe, but once encountered, after that you know it when you see it. But this is a completely different matter from a wine being corked.
The real bad part is that TCA strikes seemingly at random--some of the best estates have been afflicted. This is why quite a few top wineries are taking serious looks at non-cork enclosures.
