My story to follow is a little bit - Apples and Oranges - but my son was a division 2 scholarship bball player. Played for a high-end D2 school. At that level they only give partial scholarships but his portion was pretty reasonable.
Having said that what he earned in college scholarships paled in comparison to what we spent during his high school years in camps, AAU teams, travel and training. In retrospect we would have been better off not doing that investment or a fraction of it ... and he would have likely still earned a scholarship (he was 6'8" after all). We parents chase after that elusive college scholarship, often fruitlessly!
I have numerous friends who have gone down that path as well, and a couple who kind of 'let nature take it's course', so to speak. They avoided the club/travel team stuff until the very end of their high school, and then only with a team that understood their athlete was going to be participating in multiple sports, so they would only be participating when it worked into their season's schedule. Some of the teams say they won't accept that, and that's fine. She went on to be one of the top basketball players in the state, got 3 D-1 offers (including KU), was also one of the top volleyball players in the state, but at 5'10 isn't tall enough for D-1. Surprising her parents, she decided to take a scholarship offer to play D-2 volleyball. The point is, all those clubs can help a kid get some experience and some exposure, but the fact remains, if you are good enough, people will find you. Dominating at the state tournament, or during your season will get you noticed. Club tournaments are good for recruiters as they simply put a large number of athletes in a single location. It's not like going to a single game on a Friday night to see one player is an efficient way to see players.
It's almost criminal you have these organizations convincing parents their 5'7 outside hitter has a shot of a scholarship if she keeps playing club ball. At most, those parents should understand that investment will likely only get them a chance to play varsity high school, and if they are OK with that, fine, but giving the illusion they have a chance when they don't have the genetics is almost fraudulent. For what it's worth, my brother in law spent around 35K in fees, dues, travel, camps, etc., for his 2 daughters and their volleyball careers...which ended in high school. We used to argue regularly about how the clubs were not a smart investment, but he and his wife knew better and truly believed their path to a D-1 schollie was in their immediate future. They never even considered a D-2 was acceptable, and that rubbed off on their daughters. Their daughters were good, but not great volleyball players and when they realized they weren't going to be playing for Stanford or UCLA, they started losing interest.
