It's unclear what you're asking here. Perhaps you're just learning the game and I - and others looking at this so far - are familiar with it so communications are not great.
Damila's answer addressed the statistical issues, so I will not. Instead I'll attempt to provide some insight.
Do you see this as two Runners getting to First for the team, or just one?
I see it as one runner at first being exchanged for another while an out has been made. The out is the most important issue here, as the offensive team is only allotted three per inning, so they've just used up one and not otherwise significantly affected their odds of scoring; however, at least they avoided a double play, so have two outs left and still have one runner on the basepaths. Also, a new batter is coming up who may be more or less effective as a hitter.
If that Batter had struck out, there would still be a Runner on First with one Out.
Correct. The same is true if the batter had hit the ball in the air leading to an out without the runner advancing or the batter was called out for interfering with a defensive player's attempt to make a play.
How do you see this?
Overall, I see it as a runner still being on first base, but now one more out made. In addition to what has already been said above, there may be subtleties involved such as exchanging a fast runner for a slow one or vice versa that could affect whether the runner on first base will (eventually) score or not. If it's a game where pitchers bat (not currently applicable in Major and Minor League Baseball), maybe the pitcher will become a little more tired if he reached base - or get to rest a little if he was the runner who was out at second base.
