Not at all. Implied volatility keep changing all the time. It changes minute to minute.
Lets say an option is trading at 15 rs. Lets assume that Rs 10 reflects the intrinsic value. The remaining 5 rs will reflect the premium for time value and volatility. IV represents expected volatility of a stock for a given period of time i.e lets say till expiry. IV will fluctuate due to demand/supply. more demand for an option means more the IV will tend to rise. Thats why you will see that in bear markets put options will be expensive. Alternatively, when demand for options decreases i.e expectation comes down then volatility reduces.
All of above in layman's words for easier understanding.
