Stone steps erode with every footstep, leading to indents over time, right? But other things seem to erode on their own through time alone, so what causes that? Wind and rain? Would it therefore be correct to say that anything, if subjected to constantly running water, loses a few atoms every second and would eventually erode? Would this mean nothing is technically 100% waterproof? Or can things erode on their own without an external force? Thanks!

What you described is the natural cycle of elements on earth- rocks are eroded by wind and water , the sediments settle under the oceans- which is then pushed back up by plate tectonics. But is your question more around energy in the universe?
