You will still be able to post links in your own chat, as well as your moderators, admins, and VIPs.

Enabling this option to block links will prevent normal users from sending messages that include links. Once in the creator dashboard, expand the “Preferences” category in the left column, then click on “Moderation.” To block all messages containing links in your chat, click the “Block Hyperlinks” slider that is the fourth option from the top to the “On” position. To open the dashboard, click on your profile picture in the top-right corner, then click on “Creator Dashboard.” Click on your profile picture, then “Creator Dashboard” to configure restrictions on who can create clips of your channel content. You can ban all links from your chat in the moderation preferences of the creator dashboard. As such, it’s easier and safer to ban all links. While moderators are great at getting your chat to follow the rules, they shouldn’t be expected to check if links are malicious or not. These links will often be legitimate or only self-advertising, but occasionally these links can be malicious. One of the issues you can have in Twitch chat, though, is people sharing links.
