No - you only get a TA when the other guy also has TCAS. He may have received a TA "Traffic - Traffic".
You get TA, when another aircraft is XPDR mode C equipped, which my aircraft was. And as I understand you should get RA when another aircraft is within 600 ft even if both aircraft are in level flight, however 500 ft separation is sufficient between VFR and IFR traffic provided both are in VMC and have each other in sight. So it doesn't make sense to me.
