For Intel CPUs, this was somewhat true starting from the Pentium Pro (1995). The Pentium M (2004) introduced a technique called "micro-op fusion" that would bind multiple micro-ops together so you'd get combined micro-ops for things like "add a value from memory to a register". From that point onward, the Intel micro-ops got less and less RISCy until by Sandy Bridge (2011) they pretty much stopped resembling a RISC instruction set altogether. Other x86 implementations like K7/K8/K10 and Zen never had micro-ops that resembled RISC instructions.
