memory - Intel Xeon E-2176M Processor with 32gb of RAM how many bit the CPU has?

I have read on the internet that a 32-bit CPU can handle around 4gb RAM max,while a 64-bit CPU can reach maximum of 16gb of RAM.
How come than that on the market I can find something like this:

Intel Xeon E-2176M Processor (12MB Cache, up to 4.40 GHz)
32GB(16+16) DDR4 2666MHz SODIMM

Are they trying to trick customers via selling more RAM than what it necessary or is there something I don t know about the relation between CPU and RAM?
