Player(1).Name = 'Ivan Barrocio';
Player(1).Position = 'Point Guard';
Player(1).Height = '72';
Player(1).shirt = '22';
Player(2).Name =  'Aries Vega';
Player(2).Position = 'Shooting Guard';
Player(2).Height = '69';
player(2).shirt = '1';
Player(3).Name = 'James Webster';
Player(3).Position = 'Small Forward';
Player(3).Height = '75';
Player(3).shirt = '23';
Player(4).Name = 'Anthony Juarez';
Player(4).Position = 'Power Forward';
Player(4).Height = '76';
Player(4).shirt = '24';
Player(5).Name = 'AJ Asberry';
Player(5).Position = 'Center';
Player(5).Height = '77';
Player(5).shirt = '4';
fprintf('    Name          Position    Height      Shirt \n') 
for n=1:5
    fprintf('\t%s %s \t%g \t %g\n',Player(n).Name,Player(n).Position,Player(n).Height,Player(n).shirt)
end
I get---->   Name          Position    Height      Shirt 
Ivan Barrocio Point Guard 	55 	 50
22 	Aries Vega Shooting Guard 	54 	 57
James Webster Small Forward 	55 	 53
23 	Anthony Juarez Power Forward 	55 	 54
24 	AJ Asberry Center 	55 	 55

"Why are the 55's popping up?"

Because you are storing all of the numeric data as character, which you then supply to FPRINTF and try to convert using format string '%g' which is not suitable for text... and so FPRINTF prints the character code:

fprintf('%g\n','7')
55

There is nothing random happening here, FPRINTF is is doing the best it can with the inputs you are giving it.

The simple solution is to store numeric data as numeric, not as text like you are doing:

Player(1).Name = 'Ivan Barrocio';
Player(1).Position = 'Point Guard';
Player(1).Height = 72;
Player(1).Shirt = 22;
Player(2).Name =  'Aries Vega';
Player(2).Position = 'Shooting Guard';
Player(2).Height = 69;
Player(2).Shirt = 1;
Player(3).Name = 'James Webster';
Player(3).Position = 'Small Forward';
Player(3).Height = 75;
Player(3).Shirt = 23;
Player(4).Name = 'Anthony Juarez';
Player(4).Position = 'Power Forward';
Player(4).Height = 76;
Player(4).Shirt = 24;
Player(5).Name = 'AJ Asberry';
Player(5).Position = 'Center';
Player(5).Height = 77;
Player(5).Shirt = 4;
for k = 1:numel(Player)
    fprintf('%24s %24s %8g %8g\n', Player(k).Name, Player(k).Position, Player(k).Height, Player(k).Shirt)
end
           Ivan Barrocio              Point Guard       72       22
              Aries Vega           Shooting Guard       69        1
           James Webster            Small Forward       75       23
          Anthony Juarez            Power Forward       76       24
              AJ Asberry                   Center       77        4
