I would probably say that based on that description, it's not possible to determine if it's a good or bad crawl space

Structurally, it's certainly no problem.
Whether there is a risk of moisture depends on other factors.
Modern crawl spaces are always insulated externally and well-drained, which wasn't always the case 30 years ago.
Under the house, there should be a deep layer of gravel and then plastic that slopes from the center out towards the foundation - also not common before - but it is usually possible to check by crawling under the house and inspecting...
You can also do a moisture measurement in addition to a visual inspection.
