Thoretically you are right but practically
Tom is right that material only is absurd

You do not need material but you need only the 32 piece tablebases.

It is theoretically possible.

If the computer dimensions are 1000,000 kilometers*1000000 kilometers*1000000
kilometers and if it can remember one position in 1/10000 milimeter*1/10000
milimeter*1/10000 milmeter then it can remember 10^48 positions
and I know that it is not bigger than the number of legal positions in chess

Of course this idea is absurd like the idea of material only evaluation.
