I agree that publicly available large datasets / statistics become fairly rare below the 1600, above that level they are fairly common. But anecdotally, I once messed around with a bunch of large datasets for the purpose of comparing high-level play to lower ones, and the statistics weren't spectacularly different. Yes, the results are essentially far more random the lower you go (especially below 1800, where play is essentially a lot less accurate), but draws are still fairly common at the 1600 level. If memory serves, top-level games had around two-thirds end in a draw, while at the 1600 level, it was basically down to one third. Not what I would call uncommon, though certainly no longer the dominant result.
