It's not about you.
It is what it is. "Likely" in "likely voter poll" means "who we assume is likely to vote".
The USC/LA Times likely voter poll makes one assumption, i.e guess. Numerous other likely voter polls makes a vastly different one.
You are making zero sense. Either a poll is a likely voter poll or it is not. This tells me the USC/LA Times poll is a likely voter poll:
"In particular, to obtain the values shown in the election forecast chart, we weight each respondent's likelihood of voting for a candidate with their likelihood of voting in the presidential election. Next we calculate the mean of that number for all respondents during the last 7 days, taking into account respondent level weights based on demographics and past voting behavior. This is the estimated fraction of the population that will vote for the candidate. The graph shows the estimated fraction of the votes that a candidate will get, which is computed by dividing the estimated fraction of the population that will vote for the candidate by the estimated fraction of the population that will vote for any candidate. The latter is analogously obtained as the weighted mean of the respondents' likelihood of voting in the presidential election."
