ELI5: How come if one boxer is clearly destroying the other, the score is always still ridiculously close, like 109 to 106 or something like that?

Most boxing matches are based on the 10-point must system. One participant must score 10. The other typically scores 9, but can receive 8 or 7 due to knockdowns or a particularly lopsided round. Anything that would warrant a 6 or less usually results in a fight stoppage.

Boxing matches can vary in number of rounds, in a five-round fight, someone who loses 50-45 was pretty much dominated even though score wise it looks a lot closer. Even in a 10-round fight, stealing a couple rounds but losing the majority looks closer on the cards than may have appeared to the observer.

Boxing is also subjective and many rounds can go either way. In such cases, sometimes a judge may side with the favorite or score a 10 for one of the boxers for any number of other motivations. 

The judges are also at ring-side, so they don't have all the advantages of television, and that too could contribute to some of the variation. The judges each sit on a different side of the ring, so their vantage point is also different from one another.
