When using the Arcade Intersects() function on a point and a polyline:
Is a search tolerance used?
The reason I ask:
If I were to zoom in enough, I would think that the point would be close to the line, but wouldn’t truly intersect the line. (Unless the line has a vertex that is exactly the same as the point.)
If that’s the case, then is it implied that a certain search tolerance or buffer is used? If so, how big is the tolerance?

So even if the point were on the line it wouldn't be selected. So I suspect you want Arcade to implement the same intersect options that Arcpy does
