A little. A 128Kbps stream before lossless compression is a 128Kbps stream regardless of the encoding. Different encoding formats use different lossless compression algorithms after they perform their bitwise reductions so there are some differences but those are fairly small. As a practical example, my master FLAC library is 170GB. This library transcoded to Opus at ~250Kbps (max VBR) the replica is about 47GB. The same FLAC library transcoded to MP3 at ~250Kbps (LAME max VBR) is about 49GB.

Sounds better is true only for bit rates below 190Kbps and especially below 128Kbps where MP3 fails miserably. MP3 (LAME encoder) above 190Kbps is transparent for most sources. While Vorbis and Opus may be better than MP3 at 190Kbps and higher bit rates as measured by machines, the differences are beneath human hearing thresholds.
