You should check out the reviews on Amazon. According to what I've read, if you have a Nintendo account profile listed under a parent's or guardian's Nintendo account, you can't access those games or your profile on the Switch Lite. Only the parent's profile will be accessible. Also not all Switch games are available to be played on Switch Lite. Off the top of my head, I know that Super Mario Party is not playable on the Switch Lite and there's a whole list of other games that aren't playable as well.
