Is the data sent via WIFI directed or not?

for example laptop sends data to to wifi access point, before the radio waves reaches that device is it one big wave that anyone can see it? or its small wave directed toward that AP and no one else can see it?

Wireless is a shared medium, there's some 'beam forming' technologies out there but in general your wireless data is just spreading out like a sphere from the radio in your device.

Eh, not really like a sphere. Most monopole omni antennas look more like a donut in their radiation pattern. Directional ones are warped even more toward the front and back lobes. There will always be minimums parallel to how the antennas is pointed.
