Its only anecdotal evidence, but this would support your idea.
I used to work for a mom & pop company. The owner was really wealthy. He would only play once the pot got to an insane amount (I think it was over $5 or $10 million) and then on his way into the office, would stop at 5-8 places, buying anywhere from $1-$3K in tickets a shot.
I still vividly remember huge stacks of lottery tickets sitting on his huge desk in his office.
He never did win the big pots, but did win a $1K or $2k amounts by matching a few of the numbers. But very clearly, he spent WAY more then he ever won.
