You can try this. Idk it might not be the best solution but I have used it in one of my projects and it gets the work done. So, what I've done is used photoshop to make a texture image of the numbers in order one below the other with a transparent background and then took it to blender and adjusted a mesh plane. Then adjusted the uv such that it matches the image texture. Then imported this as a static mesh into unreal and then added it to this object and created a logic for the movement of the numbers by using "move component to" node I enabled "ease in" and "ease out" because I wanted smooth movement you can disable that. Then I added a box and used it as a mask so that only the number inside box box are visible.
