The original comment was that the cars are Clio/Golf sized instead of SUV-sized.
You countered that SUVs and crossovers are outselling other categories, but subcompact crossover SUVs like the Captur, Yaris Cross, 2008/3008, etc are, in fact, Clio/Golf sized.
So whatever statistics you're considering, if you're going just based on "type contains SUV" without considering size, then you're missing the actual important part.
If you're going based on your link's content, it also says:
"Compact SUVs (C-SUVs) were the most popular type within the category, accounting for 42% of total SUV registrations last year, followed by smaller models (B-SUVs), with 36% market share."
So that means that about a third (64% of the 54% number you're quoting) of vehicles sold are SUVs larger than the Clio/Golf size they mentioned.
And since this whole sub thread started based on a comment about vehicle sizes, it's not "moving the goalposts" to talk about the actual size of the vehicles being sold.
Of course, one could argue "it's SUV sized if it has SUV in the class name (regardless of compact or subcompact)" but I think that would be willfully sidestepping the point.
