Whenever you gamble for that long tho you are dropping the house edge as well with the extra stuff you are getting. Of course what you will get is still unknown and you have no idea but do not forget that there are races and competitions and many other stuff going on that you can't precalculate but you can count on when you gamble all that much.
The races are not going to give out a money that compensates the loss one makes by playing the race/being a part of the race. We can see the amounts given to the biggest roller right here. How much they really drop the House edge, as you claim is still doubtful here. Obviously the casino is winning more than they are losing which is why they are running the business well.
With the 1000 dollar races and many other stuff if you lose only 1% like the house edge suggests in the long run you can make up for the it in the difference with the money you make from the extra stuff.
Lets keep the races aside, PD does give away a lot of free stuff so that makes up a big amount for those who want to try the casino at the cost of essentially free coins.
Not only the races or competition neither, you can also get VIP program and even free money you can collect when you get high enough as well to continue this wagering thing. Not losing too much while gambling for a lot of money is still quite possibly a profitable thing.
Still its better to be on track about how much one is losing or winning and whether they need to stop.
