Shaoxing wine is barrel aged. That aging usually stops when bottled of jarred for sale. Any maturing is minimal to non-existent, mainly because the wine is pasteurised. Some unpasteurised wine is sold, but is rare. Even then, the maturation is minimal.
So a 2020 Shaoxing kept for 20 years will be old, yes, but no better or more mature than is was 20 years earlier. It may even be unusable. Shaoxing can deteriorate or even go 'off'.
