I am wondering about "would" can be also used to express the degree of certainty. Not any website shows any example sentences using "would" to express the degree of certainty only except for the under website. https://medium.com/@gmbley/modal-verbs-levels-of-certainty-ba14047dd134 This site only shows "would".
Anyway, I have also read this previous Q & A (Would vs will degree of certainty),
According to this, "Would" is only used under hypothetical conditional sentence like Type 2 conditional sentence?
FYI: Those example sentences are from Collins, Macmilland, and Longman dictionary.
