Incorrect. Monero can be mined using GPUs, and that is the dominant way it is mined.

Source : Mined Monero on an R9 290X until a few months ago.

If by "a few months ago" you mean prior to November 2019, then sure.

Since then the PoW is RandomX which heavily favors CPUs. I'm 99% sure there is no GPU in existence that can profitably mine Monero since then, assuming your electricity isn't free.

Monero's PoW algorithm is RandomX [1], which is optimized for CPU mining. While it is possible to mine with GPUs, it is significantly slower and unprofitable.
