I understand VPC Peering is used to establish connection between 2 VPCs. And to connect to another Application/Service in another VPC, VPC Endpoint Service is used. But can't a VPC Endpoint Service be connected via VPC peering?

A use-case/scenario will help

You can find a lot of info on VPC peering here:

https://docs.aws.amazon.com/de_de/vpc/latest/peering/what-is-vpc-peering.html

It is, like you already said - a (network) connection of two VPCs.

A VPC Endpoint gives you some more options - you could say it is build on top of the VPC peering idea.

Here is a short articel about it:

https://catalog.workshops.aws/networking/en-US/intermediate/5-vpc-endpoint-services/10-vpc-endpoint-services-overview

It also menntions some use cases, like

Application in a VPC that has no VPN or TGW access to other VPCS.
Application in a VPC which has overlapping IP addresses with the VPC you want to share it with
Sharing an application with external consumers in other AWS accounts (even via MarketPlace)
Limit the firewall rules for access to an on premise application by using Privatelink as a single point of access for all VPCs in a region
