Yes. A thin layer of gold plate tarnishes and rubs away, especially on a chain that hits the skin and on a ring that knocks a desk. The colour goes patchy. That is the plate leaving, not the gold "oxidising" in a week.
What lasts is a harder metal underneath. Stainless steel with a gold colour keeps its shape and its finish because the steel is doing the work. A brass bangle with a whisper of plate will not.
If you want pieces you can leave on, shop the gold-plated jewellery and the tarnish-free jewellery. The steel versus gold plate note is the direct comparison.
