Package versions in .yml file

It is rather a question, not an issue:

in the .yml file some of the packages are listed with older than most recent versions: 

- python>=3.5, <3.7
- cmake>=3.9, <3.11

the most recent and installed are:
                -python=3.9.7
                -cmake=3.21.2

there should not be a problem, right?

nice day,
