This is not correct and is a known weakness of RISC-V at the moment. The ARM toolchains are really good and have decades of improvements in them. This is a big issue for those who need to buy ROM in volume.
Better tools are coming online though. For example:
"One of the issues faced by RISC-V developers is that the code density of the RISC-V instruction set for deeply embedded processors does not match that of Cortex-M with existing tools."
