The way I remember it, if you tried to read a floppy from the very early 90s, or from the 80s, you'd probably have no trouble at all, even many years later. You can probably still read floppies from the 80s without issue.
However, if tried to read a floppy from the late 90s, or 2000s, even when the floppy was new, good luck! The quality of floppy disks and drives took a steep nose-dive sometime in the 90s, so even brand-new ones failed.
This. I have a few hundreds of 80s floppies (especially the less popular 3 inch CF2 format), and some from the 90s. They read well, at least as long as you don't leave them in the drive when idle (the magnetic head may affect them!). But the last decades of floppies were of horrible quality. I remember them failing after a month.
The vast majority of my 5 1/4" floppies (including "HD" 1.2MB ones) read just fine still. The vast majority (just about 100%) of my old 3.5" HD (1.44MB) floppies are unreadable. The 3.5" 720kB ones are mostly ok. Stored under the same conditions.
Also good luck trying to find a floppy drive. Yes, I'm sure you can buy one now but five or ten years from now? I'd say manufacture of the drives isn't exactly a booming business.
