There is always this one guy who does waaaaay more than the others, I am suspecting it could be the same person, since their names are hidden we can't really know if it is the same person or not but I always see a person who is doing waaaaay more than the second guy. Like is he really trying to participate in the races or is this dude is just gambling this way no matter what and the race happens to hit him while he is playing?

I remember like one day there was a 350+ btc wagered amount at the top when the closes was like 10-15, dude obviously doesn't care about the race that much, he wants to just play and while he plays the race just happens and he happens to play during the race involuntarily but probably glad he got the extra money. Still, shocking to see each time though.
