I think you're mistaken both about probabilities and time values.
You have to take in consideration the reward/risk characteristics of the two specific strategies too. Higher probability means less risk and less reward. Expectancy wise all options strategies have the same negative expectancy, and you should decide which one to use only function of your forecast of the underlying price and / or options' implied volatility.
For the same expiration, the time value depends on how far itm or otm are those options. You can't say that itm time value is lower than otm time value.

- Quote from ChrisM:
Buying OTM has low probability of winning. However, your friend is right about buying ITM options, as time value of ITMs is lower.
