You fell for Adobe's extremely confusing marketing. What they now call Lightroom (indeed version 6.5) is not actually the latest version of what used to be called Lightroom. It is a port of the version of Lightroom for iPhones and Androids to desktop operating systems and it misses many features that what used to be called Lightroom (now called Lightroom Classic) used to have. Lightroom (i.e. the port of the mobile version - Cloudy for short) can for example not print at all without going through a circumtuitous route with other software. The current version of the 'real' Lightroom - Lightroom Classic is at version 12.5 and can do all those things you see in the videos. Lightroom Cloudy has one extremely useful feature which is that all your devices (including iPhones, iPads, android tablets, Macs, PCs) will have all your photos on it and they will look the same because Cloudy stores all images in the cloud. Classic keeps all your images locally. You can sync to the cloud from Classic but the results are different and not like Cloudy where it always looks and behaves the same everywhere.
