Pelosi had the same margin in the house in 2018 and beat the far left into submission when they challenged her leadership.
Pelosi had a far bigger margin in 2018, the squaddies didn't have the votes to out her. Many of the less belligerent progressives were also put in line by their much greater hatred for Trump, the incumbent president at the time, whom they didn't want to give any wins.
Pelosi then had a similar margin to McCarthy's from 2020, but that's when their party had trifecta control and the ability to actually get something done, which imho had a disciplining effect on the far-left fringe of her caucus since they didn't want to threaten their short window of opportunity.
McCarthy is in a much more difficult position since he had a similarly razor-thin margin, but no chance of actually getting any Republican legislative priorities passed. He had neither a stick nor a carrot to make Gaetz and his posse fall in line.
--------------------
On a broader note, this difference in leadership difficulty/caucus cohesion between Democrats and Republicans is caused by a fundamental asymmetry between the two parties: Democrats have a large set of shared ideological positions, virtually all of them agree on the general direction in which they want to steer the country. Their disagreement largely comes down to how far and how quick they want to go down this path. Republicans, on the other hand, have much deeper ideological divisions within their ranks, the direction Trump or Gaetz want is very different from the direction a Romney or a McConnell want.
Additionally, Republicans generally want to reduce the scope of (the federal) government, so they're rather happy with obstruction and gridlock. By contrast, Democrats want to proactively pass legislation, want the government to shape and change the status quo. This shared goal means that neither mainstream liberals nor hardcore progressives have an interest in obstruction.
