Some, yes; some, no. That's the easiest answer. For example, there is a trade identified as form worker, which is not a Red Sealable trade.
Form workers are those who establish the foundation of a building. That is not Red Seal, yet it is one of the 200 trades. It has no other category, if you will. It's not a subcategory of another trade, whereas you will have some trades that could be considered potentially subtrades or a subdivision of a major trade.
For example, you have the Red Seal trade of an electrician, yet one of the non-Red Seal trades, identified as one of 200, is a technical electrician. Now what the exact difference between those two is, I couldn't tell you. So yes and no is the easiest answer.
