You can look at the wikipedia page for the most recent US House election:
https://en.wikipedia.org/wiki/2024_United_States_House_of_Re...
Democrats got 57.21% of the votes and 19 out of 19+7, which is 73%, which corresponds to your numbers. The chart I included above was for the 2022 election:
https://en.wikipedia.org/wiki/2022_United_States_House_of_Re...
Where Democrats got 55.59% of the vote and 57% of the seats. I'm guessing they were just basing the results on the first election after redistricting occurred, and it could have been Democrats were playing a long game with their gerrymandering about predicting how demographics would change in 2024 vs 2022? Or perhaps they gerrymandered but it didn't work in 2022 which was an off election with lower turn out, or maybe it was just a fluke either way.
The problem is that we would have to average each election over 10 years to figure out if the redistricting was actually biased or not.
Incidentally, this is why Republicans are playing a dangerous game here: If 2026 turns out to be a blue wave year like 2018 was, then watering down GOP margins in Texan districts could wind up amplifying rather than calming that wave. Trump definitely has that arrogance he had in 2018 that would lead him to pressure his allies to go in a direction with an idea that he is in a better position than he actually is. I'm really not sure why Democrats don't just let Trump shoot himself in the foot.
