Some people are very fortunate to have the funds for a cadetship and some are unfortunate.
If you have to ask your parents for money, there's nothing wrong with that.
I may not know to much about the Aviation industry, but its fair to say that it doesn't take time to realise how hard the industry is, You need to be hungry to survive and succeeded.
So at the end of the day everyone chooses different paths in the industry and we need to support one another, to many negatives.
Safe Flying!!
