Can a single number or collection of number be statistics?

Can a single number or collection of number be statistics:-

                                           Statistics should deal with aggregate of individuals rather than with individuals alone. This means that statistics does not deal with a single figure, since a single figure is incapable to provide any additional information other than itself.

So, a single number is not a statistical data but a collection of number maybe a statistical data.

For example, “Robi” a student of Dhaka university is 20 years old is not a statistical statement while the set of ages of all students in the university of Dhaka is a statistical statement.
