If the kitchen is tiled on the second floor, will it affect whether it will fall off in the future?

The time is short, even if the second floor is not capped, the tiles will generally not fall down easily. Unless the master of tiling is not professional, cutting corners, and does not follow the normal tiling procedure. But if it takes a long time, even if the tiling master is good, the wind blows, the sun, the rain, plus the tile, the cement aging, the foundation sinks, and the impact of cracking, it cannot guarantee that the tile will not fall off automatically for a long time.

Generally speaking, the tile will not fall off when it is firmly pasted, you mean that it will be ten or twenty years later, do you not want to change and renovate it after a few years?

No way! The tiles are very tight!
