I just got a Galaxy S23 about 2 weeks ago. It came with Facebook and Swiftkey as well as a bunch of Microsoft Apps. But no Tiktok, Games or other crap. Even after updating the OS nothing like that had been installed.
My guess is that a lot of people do not read anything and just rush through the initial setup process, thereby confirming things like wanting recommended apps to be installed.
Also there are some mentions of rooting here. I suggest to first give adb a try. It lets you uninstall any app without rooting (including Facebook and Swiftkey in my case).
