On Jul 30th, I received this email below. I did't know about it until I checked my spam folder.

As I was about to delete it, I realized that throughout my years of gambling, I've noticed that online casinos are much more secure compared to lotteries, you almost never receive scam emails like this one from an online casino. That's been my personal experience. Has anyone had a different experience, particularly with online crypto casinos?
Scammers do not really care about this, if your observations are correct you can be sure the discrepancy can be explained away by the results those scammers get.
So it is likely they have more success scamming people by writing an email claiming to be part of a lottery, than doing the same by claiming to be part of a casino, so I would not think too much about it and instead will concentrate on not even taking the time to open an email like that to begin with, as you do not know what kind of virus could infect your computer just by opening an email like that.
