I bought some soil from a soil place and they said it was 25% compost but I sincerely doubt it. I didn't get much in the way of tomatoes out of the beds that I just used that soil, and when I would work in the soil, it seemed mostly sand, shredded pine bark, peat, etc.

Of course I cannot make any determinations based on what you've got and what they are selling you, but 100% compost may not really be that. There is no legal definition of compost. Anything which starts to break down can be called compost. Even if it's pine bark that was shredded yesterday.
