Please tell me if I am right:
Vanilla: every iteration we pick randomly only board cards. We traverse whole decisions tree and players possible hole cards.
Chance Sampled CRM: every iteration we pick randomly board cards & players hole cards, and traverse whole decisions tree.

Am I right? If not - can you please explain me the difference in a simple words?

I'm sorry. The shortcut is "CFR" not "CRM" (I don't know why). But on forum you call it CFRM.

No, that's not correct.

Vanilla: Nothing is sampled. You traverse the whole tree, including all board card combinations.
Public chance sampling: Board cards (public information) are sampled. Obviously this is the same as vanilla if there is no public information.
Chance sampling: Board cards and hole cards (private information) are sampled.
External sampling: Chance sampling + opponent's strategy is also sampled.

etc... There is more to sample.
