Not according to a recent study. A player's rebounds, field-goal percentages, and turnovers -- in addition to points scored -- together are most valuable in producing wins. And on this composite metric -- "wins produced" -- Bryant ranks third on his team for the regular season.
"Points scored" could well be an analog for "money spent," "hours invested," or "beneficiaries served" in the world of philanthropy -- i.e., necessary, but insufficient measures for determining your most (socially) valuable programs. Rather, consider what other elements -- such as change in learning, attitudes, and behavior among beneficiaries -- that are required for accurately measuring the social value ("wins produced") you seek.
You may find a new favorite program -- or ways to improve those that you're already committed to.
