I doubt the Ancient Greeks used Delta as a symbol for change. Sounds more like Newton or Leibniz. Delta for "d" for "difference".
The Greeks didn't choose the triangle either. They imported the Phoenician letter D, which was based on the Semitic letter Dalet, which developed from the logogram for a fish or a door. Maybe influenced by the Egyptian hieroglyph for "door".

Rivers, as they flow into the ocean, bring lots of silt with them. They also tend to spread out at the mouth of the river, forming a triangle shape. And the mouth of the river is always changing.
So the delta is a triangle which changes.
