I think the same. Very rarely do people bet for relatively safe low return bets. It's the chance of a big win that is the most attractive, even though the probability of winning is proportionally lower. The lottery that raises the most money in Europe is the EuroMillions, even though it is the most difficult lottery to win. When I play roulette myself, I prefer to play a single number or a few numbers rather than red or black, which I don't find exciting, and in the end is a negative mathematical expectation. If I'm going to put money on something where the maths is against me anyway, I'd rather have a small chance of a big win than play to lose little but win little as well.
A lot of people really bet on low odds because they think it is quick and easy money. Look at the topic recently created about the gambler who lost 1.4 million $ on a 1.01 odd...
On a side note, I just noticed that I reached 100k RP again and already exchanged them. Will keep track of it to see how long it takes before I can reach it again as 95% of my RP are coming from the WOF spins.
