Your remark is true.
I should have said : As some irrational numbers as the square root
of a number not perfect square , some trascendental constants
as pi, e, sin(1) and log(2) or the results of the iteration of:
y(n+1) = 2 * y(n) ^ 2 - 1 beguining with the seed 0<y(0) <1
and y(0) <> .5

If you can prove that the digits of the square root of 2
(or of pi, or e, or sin 1, or log 2 - take your pick)
are "an example of arithmetical chaos," if you can prove
anything whatever about the digits of these numbers (beyond
their aperiodicity), then you've earned undying fame.
Start by proving that there are infinitely many sevens
in the decimal for the square root of 2.
