I doubt these newbie traders will fully understand the meaning of risk management if they don't actually experience the real risk situation in doing trades. For them to fully understand the risk management, these newbie traders should experience losses or anything worse while in progress.

Even if they read all the basics, dos and don'ts, must thing to do checklist, and prepared everything before an actual trade, they won't understand the meaning of those if they have never suffered something bad and things they didn't expect to go wrong.

Only after experiencing several bad trades will they become serious about minimizing it in the future.
