With respect, you deeply misunderstand what LR is what and it does. Aside from the auto tone button and applying presets, all of Lightroom's editing tools require informed and educated decisions from the user. It takes significant education in post processing to achieve mastery of Lightroom's develop module, let alone its other modules (this also applies to Photoshop, Capture One, etc). Literally everything is left up to the user's creative vision, and that's a very good thing.
More to the point of your original question: once one has that education, it can fairly easily transfer to any other editing program. There comes a point where post processing isn't about the nuts and bolts of a particular piece of software, but instead it's about your creative vision for your image, and you'll realize you no longer need training in each piece of software because you have a sophisticated mental model of what's possible in post processing that you can apply in any program once you become reasonably familiar with where its controls are located.
Now, if your comment was meant to be less about LR and more about jealousy over "pros" and their "latest laptops" ... well, it's time to face the facts. Your Windows 7 OS was released 11 years ago and was replaced by Windows 8 and then many significant versions of Windows 10. You are running an operating system that even Microsoft says "don't use, we're not providing support or updated any more." You aren't just a year or two behind the times... you are more than a decade behind. Instead of directing derision toward LR and the "pros" for your situation, maybe it really is time to upgrade?
