Drawing the structure of 1,3,5 - trimethylphenol

In summary, the conversation was about the correct naming of 1,3,5-trimethylphenol and the confusion surrounding the placement of the OH group and numbering. It was agreed that the pictured structure is actually 2,4,6-trimethylphenol and the question may be incorrect.

The picture above is the correct answer, but I do not understand why.
I thought that the OH group on the top has to be prioritized and be numbered 1.
But then, the structure would have to be named 2,4,6-trimethylphenol, not 1,3,5-trimethylphenol.

For example, 4-chloroaniline structure looks this way. From this structure, it seems likes NH2 group on the top did get priority.

Can anyone tell me what I am missing?
