Unfortunately, playing conditional chips will only allow you to learn the general rules of the game (for completely new players not familiar with poker), the interface of the poker client, the lobby, and customize the look of the table. And that's all.
Upgrading your game, playing for conditional chips - almost impossible. Firstly, the level of players you meet there is extremely low. Secondly - when people play free chips, people do not appreciate them, as a result they take absolutely ridiculous (usually extremely aggressive) decisions. In the third - someone just sets up his poker client and does not pay attention to what is happening at the table. All this makes the game of conditional chips extremely inadequate. What can you learn in this game? After all, you will not see reasonable judgments of strong players here.
The only exception is the section of home games, where they also play conditional chips, but here prizes are usually paid in a different way, in addition to the cash register of the poker room.
