Yes and no. The same principle still applies to any investment - don't go all in on just one investment or "invest more than you can afford to lose", but the risk of investing in stocks is lower than investing in Bitcoin, and so are the profits.
Both statements are hugely different though. Instead of $AMZN, let's use the $SPY/$VOO/$VTI/etc as an example; where it's pretty common for people to have their stock portfolio allocated to these assets with an allocation of 30% up to 70%. While it's not "all in", I definitely wouldn't say "invest more than you can afford to lose".
And yes, we can say that it's far less risky than BTC, but this part is starting to get really really subjective despite me
mostly agreeing.
And stock performance is at least to some extent can be tied to how well the company is doing, but Bitcoin short-term performance ignores all fundamentals.

Where's any guarantee that it won't crash just as fast for absolutely no good reason?
Short-mid term price movements with stocks are actually
mostly not related to fundamentals; obviously as the markets can be really really irrational at times.
And yes, bitcoin short-term performance ignores fundamentals, and yes crashes do happen obviously, but we're talking about
investing here, not trading. The stock market does crash as well! Just significantly less violent(remember the covid crash?).
The network is the same today as it was a year ago when the price was only $10,000.
It's "the same", except we literally have public companies and an actual country holding bitcoin in their balance sheets now.
