I don't think its black and white. I think sometimes success is a matter of luck. For example, in large organizations there can be a lot of roles generated where there isn't always that much direct pressure and people can be hired through luck (e.g. getting on with the boss, some types of diversity hires, being loyal to a company even if you are not that good etc.). If teams of people make products/reports etc. sometimes it can be hard to shine, and 'talkers' who don't contribute much can get promoted into a 'lucky' role.
Its not black and white.
You illustrate a perfect example of simply not understanding what people want. Talkers get promoted because talkers have social skills, and companies are social systems, and social skills are required to advance through them. Social skills are probably more desirable than technical skills most of the time. It’s not luck that these people succeed, it’s the fact that they have the qualities that people want.
You can succeed through partially through luck, like if a record executive decides they going to manufacture some massive level of fame for you. But this isn’t a viable long term strategy, only providing what people want is. Over time the variance of luck goes away. The luck outlook relies on the fallacious idea that you only get one opportunity to succeed, but you don’t, you have as long as you’re willing to keep trying. Maybe a failure on one particular day can be explained by luck, but you get to wake up and keep trying every day, and if you have what people want then luck becomes irrelevant and eventually you will succeed. That’s how basically every single successful person you’ve ever heard of has done it.
