Depends on what you want to do! The easiest way would be to find API's, SDK's, or libraries that can do all the low-level AI work for you. For example, if you want to utilize machine learning to predict the crypto market, you could use Google's Cloud AI service. I'm not really familiar with them in particular, just using them as an example: https://cloud.google.com/products/ai/
Using these services almost completely removes any theoretical knowledge you would need in order to do AI. In the future, I believe that it won't be necessary at all to study AI in order to use it in your applications.
I would recommend also just googling AI fundamentals to get a feel for the different branches that you can study.
In summary, you should be able to have some fun just from :
