Is there any difference between gigabyte ab350 gaming 3 and gigabyte ab350(matx version) gaming 3 other than form factor??

Apart from the form factor:
ATX version has 3x PCIe2.0 x1 slots (shares bandwidth with one PCIe x16) | mATX version has 1x PCIe2.0 x1 slot
ATX version has a total of 4x fan headers | mATX version has a total of 3x fan headers
ATX version has 2 out of 6 SATA ports oriented in 90-degree | mATX version has 4 out of 6 SATA ports in 90-degree

Sharing bandwidth means some PCIe x1 slots (specifically, PCIEX1_2 and PCIEX1_3) has its PCIE lanes also used by some other PCIE slots. In the Gigabyte AB350 Gaming 3 motherboard's case, it is also used by the second PCIe x16 slot (the one running in x4 speeds). This is because of the limited PCIE lanes the motherboard can be distributed for use on its ports/sockets.
In effect, when you plug any expansion card (such as a Wi-Fi Card or a Sound Card) in either PCIEX1_2 or PCIEX1_3, the second PCIe x16 slot will only run in a slower x2 speed -- it's taking (or "sharing") PCIE lanes from that slot.
The "90-degree orientation" means that in the motherboard's layout, the direction on which the said SATA ports are facing is directly towards the case's cable routing holes for better cable management. Such SATA ports are usually located along the motherboard's edges. On the other hand, when a SATA port is not oriented in 90-degree, the port is facing outwards where the cable would have to form a "loop" before it enters the cable routing hole.
Example of SATA ports not oriented in 90 degrees (poor cable routing):
