No. Deleting a slider (or uninstalling the plugin, by default) never deletes Media Library attachments — only the slider's own configuration.

Enable "Delete all plugin data on uninstall" in Settings → Advanced before deleting the plugin from the Plugins screen. This is disabled by default so your data is preserved.
