You only need %'s in macros, and then only in situations where tex stops reading:
\def\something#1% otherwise tex wants a space as delimiter
{...}
\count4=123 tex sees the space as end of number
\ifdim\dimen0=10pt idem dimension
\somemacro
{a}
{b}
{c}% only after the last one, only in hmode
\ifnum\count2=456%
789 is actually wrong!
\ifnum\count2=456 is ok
789
in normal cases no % is needed after any \abc since the space stops the scanner
etc etc
In a context text you seldom need %'s.
