Yes

Does even CZ hint that we are entering that very phase?

Most likely, the alt-season has already begun. And it started in the standard mechanics with old forgotten projects (dinosaurs), where among holders in most cases either the project itself and its market makers, or holders who got stuck from 2017 and 2021.

It's always easier to pump where there is no crowd. Few will make money from this, and most likely, during FOMO, people will rush to buy these same assets at a high. Meanwhile, liquidity will flow into other projects.

The phase begins when money quickly flows through the market. While you are analyzing some project and looking for tokens among the dinosaurs, L1 blockchains will already start to shoot, and so on in circles.

So don't try to "outplay" the market. Liquidity moves very quickly in such phases, and while you have time to think — the market has already acted. Just sit in your assets and wait for pumps, and then don’t forget to take profits in parts.
