usefull Bitrate

What bitrate may we call "professional".
May I trust Wiki?:
1 Mbit/s YouTube 480p videos (using H.264)[21]
1.15 Mbit/s max – VCD quality (using MPEG1 compression)[22]
2.5 Mbit/s YouTube 720p videos (using H.264)[21]
3.5 Mbit/s typ[clarification needed] – Standard-definition television quality (with bit-rate reduction from MPEG-2 compression)
3.8 Mbit/s YouTube 720p60 (60 FPS) videos (using H.264)[21]
4.5 Mbit/s YouTube 1080p videos (using H.264)[21]
6.8 Mbit/s YouTube 1080p60 (60 FPS) videos (using H.264)[21]
9.8 Mbit/s max – DVD (using MPEG2 compression)[23]
8 to 15 Mbit/s typ – HDTV quality (with bit-rate reduction from MPEG-4 AVC compression)
19 Mbit/s approximate – HDV 720p (using MPEG2 compression)[24]
24 Mbit/s max – AVCHD (using MPEG4 AVC compression)[25]
25 Mbit/s approximate – HDV 1080i (using MPEG2 compression)[24]
Thanks.

Inquire the particular broadcaster or streaming platform where you want to submit your program, what are their technical delivery standards for submissions.

Some examples:

The BBC: https://www.bbc.co.uk/delivery/technical-requirements/
PBS: https://www.pbs.org/about/producing-pbs/red-book/
Netflix: https://partnerhelp.netflixstudios.com/hc/en-us/articles/7262346654995-Post-Production-Branded-Delivery-Specifications

MPEG-2 4:2:2 @ 50 Mbit/s was for a long time a broadcast minimum, but the times a-changing, although I am not sure why, considering that over the air broadcast quality in the U.S. has fallen.

Thanks, great info.
I'm curious to know what the current recommended bitrates are.
Found on PBS, they ask for XDCam HD422 @ 50 Mbps.
