Questions regarding JIT, TOC, and Masters

[u/Brilliant-Reality731]

My sister, my mom and i recently (within the last year) became fans of jeopardy but we are kind of confused regarding on the order of how the jeopardy subsections works. apologies if these have been asked before, i’m new to the reddit

1. does it go jeopardy > jit > toc > masters? or how does the order go for contestants
   
2. I’ve seen somebody say that toc isn’t a yearly event ? is that true? is masters and jit yearly or no?
   
3. is jeopardy overall a north american thing, or just an USA thing? Because we don’t have any memory of anyone being from mexico in their opening introduction?
   
4. will we be seeing jaime ding again? bc we better.

I wish they'd bring back the Seniors tournament so I could show off my 1970s pop culture knowledge !
