What does the notation P(X = 5|X ≥ 3) mean in terms of random variables?

For reference, here is the full question:

Let X is a Geometric random variable with parameter p. You answers for the
following questions with be a function of p. What is the value of P(X = 5|X ≥ 3)

I don’t understand what that notation means. Is it asking for the value of P(X = 5) given that

X >= 3?
