Ok, so this is what we call a false premise.
Switch Lite is a Switch console, so anything that is a Switch console within the Switch family of devices, is a Switch. A Switch is a Switch is a Switch. Making up arbitrary rules doesn't change the data. Minor functional or cosmetic differences, and a different MSRP than the OG model doesn't stop any of those models from being considered a legitimate sale. Nice try, tho!
Your argument is weak from another angle as well, because even if you wanted to peel the Lite out of the total for some odd reason that doesn't make sense, it's by far the lowest-selling version of the Switch. So doing what you are trying to do doesn't help you very much, if your goal is to somehow argue that Switch sales are lower than they actually are.
A hypothetical PS2 Micro, for example, wouldn't have been excluded from PS2 sales, if it played PS2 games.
Alright, class is over. Go play outside!
