Universe is expanding and has been doing so since the Big Bang. So it can't be in one big clump. It would probably be a very neatly organized sparse cloud of particles if not for randomness, which caused it to stick into various blobs
Should it be construed in the way you think that the distribution of galaxies in the Universe is not random?
That's literally the opposite of what I said. This discussion is going in circles now.
There's not only one pattern in a random distribution as there are many, and their very existence makes a random distribution somewhat less random, from a practical point of view (superstitions or otherwise)
Again, that doesn't fit the basic dictionary definition of random. By definition random doesn't have patterns. If you're seeing patterns then your randomization algorithm is not good (which technically is the case with almost any human-devised algorithm) or you're not actually seeing patterns.
Going forward you probably should establish if you're discussing a specific algorithm or the hypothetical ideal randomness. There is no doubt that most algorithms have flaws limiting their entropy (but nonetheless are good enough for many practical purposes like gambling). But that doesn't mean a contradiction the way you're presenting it.
