Upon further review,  states that there are two ways sports figures are presumed notable (under Generally acceptable standards).  The first prong is met by meeting any of the qualifications in one of the sports specific sections (such as #Boxing).  As my comment states above, the guidelines are only for professional boxers, thus the national amateur titles/medals you discuss are not relevant.  However, there is a second prong is met by having participated in a major international amateur or professional competition at the highest level such as the Olympics.  I believe competing at the World Amateur Boxing Championships would meet this prong.  Many of the boxers you list are merely successful junior athletes to this point of their career.  For example, Oscar Andrade was merely a cadet national champion (cadet is usually younger than junior, so probably age 16 and under) national champion.  If any of these fighters won senior national championships for Mexico, then there is a good chance they fought at the World Amateur Boxing Championships and thus are notable.  If you can establish that a fighter did fight at the World Amateur Boxing Championships, then that would save that article from deletion.  However, merely winning a junior national medal (even gold) is well established in  as not being enough for notability
