I asked God to give me a sign

I was talking to my partner about how I was worried about us getting married. I said, “I wish God would just show me a sign like a purple horse or something so God could talk to me.” (I said that as just an example and I wasn’t serious) My partner and I prayed together so God could show me a sign and feel more peace. The next day my partner saw a purple horse video on TikTok that only 400 likes. Very random. And then an hour later I saw a purple mustang car. Are these for sure signs from God or is there a possibility that it’s from Satan?
