How much training or education is needed? I mean, frankly, a person can just go watch a 20 min YouTube video and learn all they need about how to restrict calories to lose any amount of weight they like.
You don't think people are capable of this?

Feeling like you understand something and actually understanding it are two very different things.
Let's take something as simple as "calorie deficit."
Being at a calorie deficit itself requires knowing two things:
1. How much you burn in a day (total daily energy expenditure or TDEE)
2. How much your intake is for the day
Deficit = TDEE - Intake
You can do calorie counting for #2. But what can you do for #1?
The average guy does not know how to calculate these properly, let alone judge weight movement, which can move a lot in the opposite direction due to water weight fluctuations that can exceed 1 kg+ of movement a day.
If you calculate your maintenance calories using a TDEE calculator and get 3,000 kcal, then apply a 400 kcal deficit, your target intake becomes 2,600 kcal/day.
But what if your actual maintenance drops by 300 kcal the following week?
Your effective deficit is now just 100 kcal/day, assuming your intake stays the same.
Eventually you might find yourself barely losing weight, or not seeing any noticeable change for a while. You'll start wondering, "I'm eating in a deficit, so why am I not losing weight? Is there something genetically wrong with me?"
You might even blame your metabolism.
The problem is that your original calorie target was based on a static estimate of maintenance, not a continuously updated one. Your energy expenditure changes as your body weight, activity, and other factors change. A TDEE calculator can't account for those changes in real time.
The average guy does not understand expenditure, weight movement, the calorie-to-fat equation, water-weight fluctuations, and many other gotchas, and no, 20 minutes may not be enough to understand all this for an average Joe.
