@RobinHood having been person 1 (it was $1000 and help buying tires, the first time my folks actually helped with car expenses of any kind) I'd suggest the difference is that person 1 spent time without the help and understands that it doesn't just naturally show up out of nowhere. Person 2 just kinda assumes it just happens, maybe.
@Leucrotta @RobinHood also, there is a subtype of person 2, that considers their parents as contractually forced to give them lots of money, and that will make a huge fuss if they don't recieve it.
