Here is my very simple and feeble understanding of such zachen:
Teva is constantly and always affected/changed by the koach Ha’Torah (e.g., klal yisroel learing torah and keeping the mitzvos or, rachmana litzlan, the opposite). Not always in the sense of le’maaleh min hateva outside otf nature, but, within the confines of Hashem’s creation of nature things that would or would not otherwise have occured are “decided” (kavayachol) by our actions or inactions.
Everything we as klal yisroel do has a direct cause and effect on this world (and the upper worlds as well) and there is ZERO happenstance or coincidence in this world. The connection you have made is an intriguing and fascinating one, however, as a word of caution, while we may know that Hashem is the orchestrator of it all, we do not know the cause and effect of any of it.
Therefore, while we do not know WHY Hashem caused this bullfighter to die right after thousands of yidden learned about such a case in Gemara,that does not preclude us from taking mussar and lessons from such an amazing sequence that Hashem performed in front of our eyes.
