Symetric is a wing that is the same on Boaty sides. It has no vertical lift (the thing that makes the wing go up slightly). Should be used on high speed planes.
Semi-symmetric wings create a little bit of vertical lift. The bottom side of the wing is less curved than the top, causing the air to deflect down slightly. Used for medium speed planes, such as airliners. This shouldn't be used on vertical stabilisers as it will make the plane drift.
Flat bottom wings create a lot of vertical lift. The bottom side of the wing is flat so it deflects the air down. It creates a lot of vertical lift. Flat bottom wings are really resistant to stalling, so they are used with planes that have high wing loads, or STOL (Stands for Short Takeoff Or Landing).
BTW You can test it by building a plane and making the wing types different on each primary wing.

So if you're making primary wings, don't use symmetric
Symmetric provides no lift and is used in the vertical stabilizer and I forgot the difference between the other two
