Look, this article has the statistics:

I have read this and I came to a conclusion
This gamble is very stupid, for all I know, the old guy is tricking the young guy to switch, because human psyche and stuff, and our very smart guy switch, saying base on math, he would have 66% chance to win.
Excuse me, on the 2nd chapter, he is cheating in a gamble, he plays with human mind, and now he just follow the fucking math.
The read about math was fun, but this chapter is utterly stupid
And what happened when he lost, he win a deal anyway.
This whole chapter feels forced
Edit: After reading another link https://betterexplained.com/articles/understanding-the-monty-hall-problem/ I have now understood
Especially this
Do you stick with your original door (1/100), or the other door, which was filtered from 99? (Try this in the simulator game; use 10 doors instead of 100).
I guess it does make a sense to choose the other one, but damn, I still don't feel this is good choice as a gambler.
