Numerically means “in numbers” or “if you look only at the figures.” “The other team is numerically stronger” means they have more players, not that they play better. “Numerically, the risk is small” means the count looks small, even if the danger still feels large. People use it when they want to separate the raw numbers from everything else that might matter — quality, feeling, fairness, skill. It is a slightly formal adverb. In speech you can often say “in numbers” or “on paper” instead. You will see it in news, reports, and careful comparison.
