It doesn’t seem like that. Related your example to their comment, the very presence of Google is causally linked to the tiny chance of being the next Google Chrome, because Google has monopoly power in search and is leveraging that to power in browser competition. ‘Winner takes all’ markets are created, and can be disassembled.

The OP comment is pointing out that to survive and thrive in the browser market an entrant has to seek revenue from its dominant competitor. That is not simply a reality of some businesses being big and some businesses being large. That is anti-competitive.
