we use & to display & in html in case the browser can't recognize &? Is that correct? Or is that just a html way of displaying &??Do we have to do that for all symbols???

Yes, because the ampersand (&) by itself starts an escaping sequence that the browser will convert to whatever symbol it means. Another example would be the less-than symbol (<). By itself it means the beginning of a tag, so if you just have it in your HTML the browser would assume a tag follows, and nothing would get displayed. To display the actual symbol, you would do
Thus, any symbol that is either reserved (<, >, &, ', ") or "weird" (e.g. ÷, Ç) should be displayed by escaping with
&. And since
& itself is reserved for escaping, you would display it with
& instead of just having it in your HTML text file.
