Because precession happens approximately 20000 years and given the fact that during our summers, we are farthest from the sun. Does this mean in 10000 years we will be closest to the sun during the summer and farthest during winter?

Good question. Actually, Earth's perihelion precesses too, but at a different rate from its tilt. According to this site - http://www.astrosociety.org/education/publications/tnl/45/globe4.html - the observed perihelion precession is about 11arc-seconds per year, compared to 50"/year for the equinox. The perihelion and the equinox are moving in opposite directions.

yes...in 10,000 years winter will be when summer is now.
But this has nothing to do with closeness to the sun.
It only means a different angle relative to the stars.
