It does not matter.
The ELO system is based on the principle that winning percentages can be turned
into rating differences.
It's not me who brought statistics into the chess world. The chess world itself,
by accepting the ELO system, admitted that statistics are an useful tool to
analyze the chess matches results.
And statistics are not only coin tossing. Statistics help us to understand the
world, and sometimes it is the only tool we have to understand very important
phenomena.
Using statistics to understand the results of chess matches does not mean that
chess is like coin tossing.
