I want, upon starting my function, for one of 5 text statements to be printed. There should be 1/5 chance of any one appearing, and the text printed should generally change with each run. How could I go about doing this? Additionally, if I wanted to change the text statements to choose from (7 instead of 5), how would I do that?

Use randi to choose an integer between 1 and the number of strings, use that to index into a cell array of char vector or a string array:
texts = ["some text", "some other text", "and more", "etc."];
selectedtext = randi(numel(texts));
disp(texts(selectedtext))
