a very nooby question

I think even to most FPGA lions, it's still pixie dust inside the LUTs and Registers. So yes, there are gates that make up these structures, but we don't know how many or exactly how they're put together, and to a certain degree don't care since there's nothing you can do with that information. The LUT/reg is really the DNA building block that you can target/manipulate. (And more in more designs don't look at that, since designs are getting so big, it's like assembly when writing a large program)
