I have a polygon layer that shows a parking area where one of the attributes is the number of parking spaces. I would like to get, instead of a polygon, a layer of points that will be evenly scattered over the polygon and the number of these dots for the polygon depends on the attribute "number of spaces". 

An example:

They aren't going to look nice, but you could check out the Random Points tool:

https://pro.arcgis.com/en/pro-app/latest/tool-reference/data-management/create-random-points.htm

With it, you can constrain the points to the polygons and use the "number of spaces" field to tell it how many points you want. You can also specify a minimum area to help get the points a little more evenly spaced. I imagine you could get a decent enough output this way.

How many polygons do you have to fill? Is it feasible to digitize the points manually? There are other editing tools besides manually placing points, like placing points along a line.

I have more than 15k objects and I,m aware of the tool Random Points but I was hoping that a more accurate solution was still possible.

On the other hand the tool "create  point features along a line" is not a good idea because its impossible to create a line from polygons because of the fact that there are many ot them with a very complicated shape.
