We study the two-point correlation $K^m_n(z,w)$ between zeros and critical points of Gaussian random holomorphic sections $s_n \in H^0(M,L^n)$ of powers of a positive holomorphic line bundle $(L,h)$ over a K\"ahler manifold $(M,\omega)$ of complex $m$-dimensional. The critical points are points $\nabla_{h^n} s_n=0$ where $\nabla_{h^n}$ is the smooth Chern connection with respect to the Hermitian metric $h^n$. The main result is that the rescaling limit of $K^m_n(z_0+\frac u{\sqrt n}, z_0+\frac v{\sqrt n})$ for any $z_0\in M$ is universal as $n$ tends to infinity. In fact, the universal rescaling limit is the two-point correlation between zeros and critical points of Gaussian analytic functions for the Bargmann-Fock space of level $1$. Furthermore, there is a 'repulsion' between zeros and critical points for the short range; and a 'neutrality' for the long range.
