Is sample size of 1 consider Reservoir Sampling?

I just want to know that my code is reservoir sampling. I have a stream of pageviews that I just want to process. I'm processing one pageview at a time. However, since most of the pageviews are the same so I just want to randomly pick any pageview (one at a time to process). For example, I have a pageview of

[www.example.com, www.example.com, www.example1.com, www.example3.com, ...]

I'm processing one element at a time. Here's my code.

import random

def __init__(self):
  self.counter = 0

def processable():
  self.counter += 1
  return random.random() < 1.0 / self.counter
