i don't think so.

because people usually don't use good strategies and they are wasting their money in most of these gambling sites.

for example i have seen new dice sites that start off with a 0% house edge and there aren't that many winners on the site to win and bankrupt the casino.

house edge is like a guarantee in my opinion.

and also add to this, the fact that a lot of the gamblers will continue gambling when they win and if a losing streak hits them they lose all they have won so far.
