RISC is used essentially everywhere except for laptops/desktops. Also, RISC teaches you the fundamentals better, especially considering that you can design a simple RISC architecture pretty easily. Also, ARM is being moved into the laptop world (Chromebooks, and possibly the 2020 Macbooks), RISC-V is being pushed for by everyone, you can make a POWER9 desktop for ~1.5k (or buy for 2k), and you also have SBCs like the Raspberry Pi and others. On top of that, Windows 10 now has ARM versions, Linux and NetBSD have been ported to RISC-V, ARM, MIPS, POWER9, and everything else that you can think of, and XNU (the macOS kernel) already has an ARM version (iOS core). Practically, even when writing for a CISC processor, most of what you do will be RISC-y either way, since most of your code is gonna be taken up by a few simpler instructions. In my opinion, go with a RISC, specifically ARM or RISC-V if you want to ever use your skills in the real world.
