No.. they're not. Do you understand random (the apparent or actual lack of definite patterns or predictability[0]) or compression (reduces bits by identifying and eliminating statistical redundancy[1])?

I could write a program to generate the first 100MB of pi in a couple kilobytes. That certainly counts as “data compression” but isn’t useful outside this particular problem instance.

Over infinite runs, you can't compress random data, but that doesn't mean any finite string of random digits is incompressible

by this definition, a random dataset could apparently present no patterns, while presenting non apparent patterns.
