If you go to a flight training school for the purpose of obtaining the requisite training that leads to the aquisition of a commercial pilots licence, why would you be surprised that the schools were selling you into the idea of being a pilot? What else are you going there for? The schools are commercial enterprises and naturally want your business. It would only be a scam if they failed to provide you with the training you had paid for.
A licence is just a licence. It leaves you with a piece of paper that grants you certain priviliges and nothing or little more than minimal experience. The misconception that many people have is that there is a whole world of glamorous employment opportunities just waiting for them to complete that training. There isn't! It is just one low rung on a very long and expensive ladder.
Many people have been successful climbing that ladder and a very few have been in the fortunate position of being winched to the top. For the vast majority it involves a lot of time, effort and little reward. There is also a significant attrition rate in that many give up or are forced to give up. It is like any other pyramid with a very wide base and a very small apex. The perceived glamorous jobs are much closer to the apex than they are to the base. The licence you have acquired places you firmly at a highly populated base.
How you find your way to the desired level is not the flying schools job or their concern. If you need to progress higher they will undoubtably be able to sell you facilitatory tools, but they will not in themselves guarantee you much. Nevertheless these schools can sell you the basics and it is the basics you will need before you can even hope to progress any higher.
As a potential customer it is you who needs to properly asess the risk. You need the product they are selling in order to be a player. As a player you are embarking on a reasonably high risk pursuit. The degree of risk varies as does the economy, but it is always significant. The schools are businesses and will always gloss the product. Prestige car manufacturers will also sell you a 90k product without any qualms as to the advisability of your decision to purchase that product. They are happy to suggest that their 90k product will bring you success and happiness. If it doesn't that is your problem! The only difference is that their product may at least have a residual value. Flight training doesn't which makes it a harder sell, unless the purchaser can convince themselves that they need this product.
There are no guarantees. It is very unlikely that you will complete this training and find the sort of job you expect, or indeed any job. You might be very lucky, but you should prepare yourself properly by assuming that you will need a lot of additional personal investment in both time and money to stand any realistic chance. To answer your question, usually nothing happens after you obtain the licence. You realise that you have joined a very big crowd of people wondering what to do next.
