I don't know a single kid that would not know which models are current gen and which are better or worse. Argument about non technical parents is valid but any kid today will know which Xbox to get and will tell their parents. Kids these days know much more stuff than you seem to think, they spent 1/3-1/4 of their lives on the internet. My 11-12yo nephews built PCs just following youtube guides, they do video montages of their Fortnite games to put on youtube and almost every single friend of theirs is similarly familiar with current tech.
Xbox having lower numbers is purely fault of PS dominating the market over last decade, people will continue buying it cause they trust Sony to deliver exclusives and they have existing game libraries. I converted two Sony fanboys to Xbox with Game Pass and they both love it. Noone these days buys a PS "because they are confused with Xbox naming", 5 minutes of googling answers any questions. The only people who might really have an issue with this are boomers+ who are not even going to buy a console for themselves cause "games are for kids and a waste of time".
