You may not have quite got what fnordianslip wrote.

When linux reads some data from disk, it leaves it in RAM, just in case it needs the data again. When all the RAM has been used and more data is read, it replaces data that has not been reread very often or was read the longest time ago. If All the RAM is being used by running programs, then some data is moved from RAM to swap.

A lot of data is read by linux just booting, so very little RAM is ever completely free.
