This is the #1 source of confusion. A motherboard may have three long x16 slots, but only one of them actually has 16 lanes of data.

PCIe sizes refer to the physical and logical configurations of the interface. The most common PCIe sizes are: PCIe sizes refer to the physical and logical
When building a PC or upgrading components, you will encounter PCIe (Peripheral Component Interconnect Express) slots. While they all serve the same purpose—connecting components like graphics cards and SSDs to the motherboard—they come in various physical sizes.
PCI Express (PCIe) sizes refer to the physical length of the expansion slots on a motherboard and the number of high-speed data "lanes" they provide . These sizes are critical because they dictate what hardware—like graphics cards or SSDs—can fit into a computer and how much data they can transfer.
