I don't necessarily think that that is true, as almost every social science has been turned into maths one way or another, beginning with Economics. Heck, even mundane stuff like sports (think football/soccer) has now been absorbed by data, which you can see as applied maths.
Yes, I do know that advanced maths doesn't currently explain Arteta's system at Arsenal but we're generally talking about that same semantic area of interest, i.e. if the interest on maths were to subside as a result of AI taking that interest away from us then we will have no more data/stats-focused Artetas in the future (and possible no AI-like thingie also).
