No. Consent is only needed for data you collect which is unnecessary to provide the service you are offering and is unexpected by the user. If you require an email address for a mailing list or notifications, you do not need consent. If you have webserver logs containing IP addressees you use for debugging and abuse prevention, you do not need consent (though you probably want to not hang onto them for longer than necessary for those purposes). Same with names and addresses for billing and shipping, etc. If you collect data for analytics or targeted advertising, you need consent (which means rejecting that option needs to be the default and at least as easy as accepting in the dialog, something which many of these dialogues fail at. If it takes more clicks to close the dialog without 'accepting', that is not GDPR compliant in the view of most regulators).
