In general you're correct, the universe is expanding.
However, in the expansion, there's still lots of opportunity for individual pieces to mix and recombine, dance around each other, etc. That's how structures like spiral galaxies formed in the first place -- they weren't created as spirals and so forth from the beginning -- they gained their shapes over immense stretches of time. On a smaller scale, explosions of huge stars or groups of stars stir the pot, black holes create distortions, etc. It's incredibly slow and stately, one might say graceful, in the literal sense of being an expression of God's Grace.
The Creation is beyond our comprehension, but it sure is pretty, and fun to marvel at.
Don't wallow in your own ignorance. Just a tip.
