But most of the gamblers dont really like to chat instead they wanna focus on their game strategy and not likely to have disturbances while playing
This is wrong, everyone enjoys to be in a chat box that has a lot of talks and funny discussions.
Discussion, trash talks, gossips, all these make for a more entertaining experience in a gambling site. Though i think this feature is more prominent in pvp games like poker so you really get to interact with other players or with audiences watching the same table.
