ETA: It's true, life coaches (and homeopathy peddlers) often do just fine with their 1-on-1 or 1-to-many coaching.

Coaching is not primarily about giving advice. Some of them even have a ethical codex against pushing their solution onto clients.

It is basically about asking people: "What do you think you have to do? Don't tell me bullshit, what do you really think would be best for you? When will you do it?" Then next week: "Did you do last week what you said at the last meeting?"

A coach helps you to go where you have ugh fields. There are plenty of people who get value from it.
