Yes, thats right. Unfortunately, you won't be able to get your 4 16x GPUs even with Threadripper, because there are always at least 4 Lanes reserved for the Chipset. The only option to get 4 times 16x on your GPUs it to go with a server platform like EPYC, which has 128 Lanes (as Longtail already mentioned). But since running GPUs with 4x is fine already (especially with PCIe 4.0), you should not worry all too much about it. The rig I have built is running 4 GPUs in a 16x/8x/16x/8x configuration, which is perfectly fine.
