No, it's not. It can be expressed as a number, but it is not a number.
Keys are purely numbers, they are nothing else. Signatures are pure
primitive facts encoded as numbers (authority X blessed object Y).
A computer program is a set of instructions to accomplish a particular
result. It can be expressed as a number, but that doesn't mean it is a
number.
It might be true in principle to develop a scheme whereby every physical
object uniquely corresponds to an extremely large number. That doesn't turn
physical objects into numbers.
