I don’t think that argument makes sense. The more money one donates, the more funds will likely be distributed to causes of all types, including private ones. While you can’t be certain your specific donation caused an increase in funding to private causes, you can be relatively confident that on average such donations will do so.
This is just like how you can’t guarantee buying meat will kill more animals, but you can be relatively confident it will do so on average.
