No, a white hole is like the opposite of a black hole, so it’s like a singularity of negative matter. If the universe is a flat plane normally, a black hole is like a pit and a while hole is like a mountain. The big difference is that white hole spacetime become flat at infinite distance in space just like black holes. Big Bang spacetime becomes flat at infinite distance in time.
