Errors should certainly be as helpful and clear as possible, but no the developers are not trying to directly attack you specifically if they aren’t, or if they wrote something they thought was fun.
Yeesh, get a grip.
If I got this error message while trying to buy a train ticket, I'd be thinking "Ok, who do I talk to to get this sorted out"
I don't understand the sort of person who stops to think "How dare this error message trivialize my Very Important Problem! I feel bad now because the words on this screen are too silly!"
