It can be difficult to Id seedlings. It’s much easier to identify the parent trees (assuming they’re around).
If you can, get closeup pictures of the bark, trunk, needles, buds, and cones of the mature pines around where you found it. Take a sample, if it’s not private property.
For what it’s worth, at a distance, those trees in your picture do not look like scots to me. The needles appear more densely spaced than what I’ve seen with for the species, especially at the branch tips.
I here that loblolly and slash pine are commercially planted in Brazil. Perhaps you have one of those.
