Sorry, but you just dismissed polling as "pseudo-scientific", and then immediately followed it up with declaring that Yang has generated far more buzz and publicity. That's nonsense.
If you genuinely think Booker has a much better chance than Yang, then you're living in a bubble. It's not only that Yang isn't well-known, because even among respondents who know about him he's just not very popular. And it's not like he's a newcomer to the race either. He declared as a candidate before basically anyone else.
I very much doubt Booker is going to make any kind of splash, but if Yang wins more than 2% of the vote in any state I'll be shocked.
