I'd love to see one of those posters explain to me, rationally, how exactly they perceive it to be fun? Please try to explain yourself rationally (with broken English if necessary).
It's rare to see a user who behaves like that here in the forum.
Try to find a gambling forum section wherein users are not involved in a paid posts feature or not crypto-related forum so that the discussion will also include how fiat gamblers behave especially those who go in a physical casino to gamble. We can have a much more accurate answer if we asked them that question compare here.
Gambling for fun does have a different meaning. But sometimes, it's just a product of others' own view to reply here without the actual purpose they really do gambling for fun.
