Are you referring to the "Top all-time" list? That list seems to be mostly filled with popular books that do not go into too much detail, which is required for a decent treatment of probability and statistics.
There is a separate topic "Data & Statistics" that has quite some relevant titles.
Also, I think the interest in probability theory has only recently grown with the advent of generative AI. I'm expecting more interest in the future.
Edit: also, the site seems to miss some nice gems, most likely because they are not traditionally published books: "Probabilistic Artificial Intelligence" is freely available on Arxiv, and was discussed on Hacker News in March 2025 [1].
