It could mean "hope" for young players with something to prove. It's "another day at the office" for players in their prime who need not worry about their spot on a team.
For veterans, it can be any number of things. One is a period of necessary warm-up. Aging veterans can take some time to get back into game shape.
For other veterans, spring training can seem like an arduous experience, one they'd love to skip if they could. Perhaps that's why every year there are veterans who have had long and successful major league careers that struggle, and struggle mightily, to perform in spring training.
More often than not, these struggles mean nothing.

Every now and then, it can be a sign that the skills that they relied on for years are beginning to decline.
