I might be a little pedantic here, but technically it is a convex combination right? Or is there a case where $\alpha, \beta$ and $\gamma$ can be negative? I thought since they are ratios of areas they have to be non-negative.

Yes, if the point is inside the triangle then it's a convex combination. In general, it's an affine combination.
