While Dan may be mildly, yet entertainingly, overstating things, he is not too far off the mark [just by a couple of orders of magnitude ;-)]:
OK, some of those may be about deleteing, correcting, or editing wrong answers, but the question has been asked many times before, not just on SE Meta, but also on the individual Meta sites.
Yes, sometimes there is a crowd mentality that prevails and the wrong answer can, even over time, get substantially more votes than the correct one. Having the wrong answer accepted by the OP can also accentuate this "erroneous" voting. I have seen some examples of this, across various SE sites.
However, generally, even if the wrong answer has been accepted, the votes tend to go with the correct answer, over time. Unless, of course, it is an obscure question and/or it is on a site with little traffic, such as a Beta site. In such a case, the two answers may only get, for example, 5 votes between them, in which case, the erroneous answer could look like the correct one, as accepted by the "crowd", albeit a small one.
You have only been on SE for two days. Relax a little, things don't necessarily happen that fast on SE. Even though you have racked up 12 answers in a few hours, other people here may not have the energy, nor the time, to keep the votes coming as quickly as you would like.
