Some languages, such as Japanese or Spanish, have three pronouns for location to mean here, there, and some distance farther away. English does not. Along with other expressions, "over there" can fill in for the pronoun that means "farther away", at least in terms of visible physical distance.
Which is to say, when talking about physical distances (usually with locations that are visible from where you stand) "over there" may imply a greater distance than using "there" by itself.
It's so crowded at the beach today! I do see a patch of empty sand over there, if you don't mind walking.
The challenge is that "there" can also be used for figurative distances, so by itself it doesn't mean "relatively close". Example:
A: I'd like to visit France.
B: Me too! Maybe we can go there someday.
Furthermore, "over there" can also imply crossing over some object or barrier, such as the Atlantic Ocean:
(Two people living in the United States)
A: I'd like to visit France.
B: Me too! Maybe we can go over there someday.
Here "over" not only implies greater distance, but also that you have to cross over the ocean to get there.
To make things more confusing, sometimes "over there" simply emphasizes the direction of the location:
If you're looking for your keys, they're over there on the table (pointing).
Anyway, this is probably not a comprehensive list of all the possible meanings for "over there". You may have to judge what the speaker means from context. Also, it is not the only possible expression to indicate distance or direction, as "out there", "up there", "down there", and various others can also mean the same thing.
In your example, To get an opportunity means the same as to have an opportunity, so, in your example, both phrases mean the same thing, and they both sound fine.

"He is gone out" is not idiomatic English. It treats "gone out" as an adjective or other description of state. This is not usual.
"He has gone out" is normal present perfect construction. It is saying that, at some point in the past, he went out. Usually, this means he's not in at the moment, though it will occasionally be used when he's already come back - though "he has been out" is more usual, then.
Both contract naturally to "he's gone out", which may be a source of confusion.
If you want to use a descriptive present tense to describe his state, given that he's gone out, you use out as an adjective: "he is out", or contracted to "he's out".
n.b.: You will find "he is gone out" and similar constructions, using is instead of have for the present perfect, in older texts. It was once a normal thing, but hasn't been for some time.
