The word ‘all’ refers to more than two and several in general; if there are only two factors involved then we must call them as ‘both’ rather than 'all'.
Point 2 is that, ‘more’ is used only when two factors are involved. ‘The most' is used when more than two are involved. I do not think the adverb ‘probably’ plays a role in choosing between ‘the more’ and ‘the most’.
