In quantum mechanics electron in general has no position. It is not that we do not know what is the position, it literally has no such property. Kind of like color has no taste. It makes no sense to talk about position of electron (in general), just like it makes no sense to talk about taste of color blue. So the picture of racing electrons is just wrong.
All we can say is what probability is to find electron at certain area. Orbital is simply put just wave function that encodes this probability if it would be filled by some electron.
The pictures of orbitals you can see are just areas of space, where the probability density of finding the electron there is bigger than certain number - if it would be filled.
Answering the comment:
"...electron has no position..." seems to contradict "...we can say the probability to find electron at certain area..."
it only seems that way. It has not position before the collapse of the wave function, but it has immediately after the collapse. The measurement forces the electron to take up the position.
