What kind of game do you want to make? There is a huge variety of SC2 maps out there. You should first know where to find the editor. It's on the battle.net launcher above the play button. See the image attached below.
Then you should decide what kind of game you want and then plan out what features you want. It's like starting any other creative project. You can search online (or in this forum) or make more posts if you need help. In terms of map design, you can make pretty much whatever you want. Some people have made really crazy things like first person shooters, 3rd person games, or flight simulators that don't really seem possible in SC2. For a beginner, you should stick with something simple that can reuse the features of the SC2 engine.

Doesn't really answer OP's question. I don't think OP was looking for online casino games.
