Does it mean anything if a guy replies late?

Does it mean anything if a guy replies late to your message or is it just the way they text? Because the guy I text sometimes replies late but sometimes replies quick and when I left him on seen for a bit I noticed he was on Instagram a bit more and then when I texted him, he responded quicker like the quickest he has ever responded and he liked my message.

I don't know if I should still give him a chance or not or just try to talk to him in person instead if that's the way he texts. But we don't know each other but he still decided to respond to me in the first place when I first texted him.
