You are right about the order of magnitude of the percentages, but the CPUs <10 W are in phones, tablets, small SBCs (single-board computers) and only in a small fraction of laptops and mini-PCs.
The vast majority of laptops and mini-PCs uses more powerful CPUs. While 15 W CPUs were normal many years ago, when Intel launched the "Ultrabook" campaign, in recent years, due to better cooling, most laptops and mini-PCs use 25 W to 30 W CPUs, and a significant fraction of them (bigger than the fraction of the laptops/mini-PCs that uses <=10 W CPUs) uses CPUs with a TDP between 35 W and 65 W.
