I wanted to check if the above picture means if I pick k = 3, then:

Yes. As for why, consider a geometric interpretation:
The area contained in at least one of the sets (i.e. $\mathbb P(A \cup B \cup C)$) is no bigger than the sum of their individual areas (i.e. $\mathbb P(A) + \mathbb P(B) + \mathbb P(C)$).
