Yes, that’s why OP cited the Congressional popular vote. What’s happening is that both parties gerrymander, so it largely cancels out. For example in Maryland, democrats won 65% of the 2022 Congressional popular vote, but hold 87.5% of the House seats. The 450,000 or so excess Republican votes—votes for republicans which didn’t contribute to a Republican house seat—cancels out some excess Democratic votes in Montana or Wyoming.
