What is the implicit meaning of abstaining from voting at the UN? [closed]

Recently, India abstained from voting against China regarding the Uyghur persecution question.

What does it imply when a country abstains from voting at any of the UN councils?

In the case of the UNSC, it means:

If a permanent member does not fully agree with a proposed resolution but does not wish to cast a veto, it may choose to abstain, thus allowing the resolution to be adopted if it obtains the required number of nine favourable votes.

In plain English, it translates into:

Neither do I agree with the resolution, nor do I care about it. Therefore, do whatever you have to do.

Can someone verify this?

And, what does it mean in the case of Indian abstinence from the recent voting at UNHCR?
