Hello,

Firstly i am confused but let me explain in simple words:

• Computer science engineering is related to every thing that's inside the computer that is the software.
• For pursuing computer science engineering you need to interested in learning programming language .
• Ai stands for artificial intelligence and ml stands for machine learning they both are combined courses.
• Basic difference between these two is artificial intelligence is used to create program or create  by using human intelligence where machine learning is the application of what you learn in AI .
• Example of AI is Siri, alpha go etc.
• Machine learning is program like eMail , spam protection etc.

As for CS and CSE there is only a basic difference that is CS is purely related to software engineering whereas CSE is hardware plus software .

Hope it helps!!
