If you look at the deadlifting example a little differently: you can get to the 95th percentile of 'people who go to the gym and actually deadlift' in terms of form and being able to lift relative to your height/weight/size/sex/muscle mass/etc.
All of the examples in this post perfectly apply to this situation: people don't record themselves and check form, don't upload those videos to the internet and get feedback, and don't get help from a personal trainer (one who actually knows something about form). This is why you see people in the gym all the time making basic mistakes: rounded back, non-vertical bar path, bending over too much/not enough.
They have more injuries, don't make progress, or don't get the results they want. Yes, you're not going to get to the top 5% in terms of weight lifted without a lot of dedication and time. But that's more of achievement over time/a career than your ability to execute the skill.
