Of course a put can lose money even if it is ITM for example if you pay $400 for it, and it finishes $1 ITM, you would lose ~$300.
The only thing I would say is that some people might (incorrectly) say their put is "in the money" when they are profitable, but it is not actually ITM yet.
For example if XYZ was at $50, and a person bought a $45 strike put for $200 - a week later XYZ is at $46 and the put is $350. The person talking in a bit of slang might say their trade (their Put) is in the money (even though the put is out of the money still).
Thats the only way I can figure someone could think that ITM automatically means profitable
