Yes hopefully you understand now.  Gold has an infinite supply, it's inflation is based on price.  As the price of gold increases it's more cost effective to mine it, increasing inflation.

Bitcoin is absolutely scarce.  It has a fixed supply of 21 million, which is issued over the first 120 or so years.  This fixed supply does not suffer from inflation because it is impossible to increase the supply of bitcoin.

Hopefully this is clear to you now.
