Code to UML - Does an association exist if a class uses another classes methods? [duplicate]

Having difficulty finding any information that relates to UML's too coding examples.
(Insert Scores Method is missing from the UML - ignore this, I am changing it now)
The Choice class uses methods from the Scores class, does this mean that there is a link between the classes? There is plenty of information regarding inheritance however, it seems.
I have created a UML:
Choice to Score Link
Choice Method
//Attributes Check
public int CheckVariables(int optionR, int optionV, int TurnCount, string Username)
{
if (optionR >= 100 || optionV <= 0)
{
//return 2; //Win
var Score = new Score();
if(Score.InsertScores(TurnCount,Username) == true)
{
return 3;
}
else
{
return 2;
}
}
else if (optionR <= 0 || optionV >= 100)
{
return 1; //Lose
}
else
{
return 0; //Not Finished
}
}
Score Method
public bool InsertScores(int ScoreValue,string Username)
{
ShowScores(); //Populate Lists with Highscores
if(ScoreValue < Turns[9])
{
SqlCommand sql = new SqlCommand("UPDATE gameScores SET scoreValue = @scoreValue, username = @Username WHERE scoreid = @ScoreId;", con);
sql.Parameters.AddWithValue("@scoreValue", ScoreValue);
sql.Parameters.AddWithValue("@Username", Username);
sql.Parameters.AddWithValue("@ScoreId", ScoreID[9]);
//Insert
sql.ExecuteNonQuery();
return true;
}
else
{
return false;
}

Per the UML specification: "The objective of UML is to provide system
architects, software engineers, and software developers with tools for analysis, design, and implementation of softwarebased
systems as well as for modeling business and similar processes.".
This means that whether you consider "dependency" and "inheritance" equivalent depends upon your representation. Based on your images, you are defining a "meta-model" model relationship as defined by section 7.11 of the specification: https://www.omg.org/spec/UML/2.4.1/About-UML/
If you have some class A that uses methods of class B then the relationship can be modeled as 11.7.1 ElementImport.
The only real difference here is what edge descriptor you use:
That being said, I would urge against mixing inheritance and dependency model diagrams and to complete your current diagram, not include the import.
