"please advise if i still need to in
Does that mean if I still need to thin?
If the picture is how they are looking now, then yes, most definitely, you still need to thin. I wouldn't try doing it at least until they get true leaves; in the picture it doesn't look like they have that. Let them get true leaves and a little bit bigger. Then you are going to have to thin A LOT. If you have more places to put seedlings, you can transplant some into other pots. But you likely have way more little plants there than you are going to have room for and some are going to have to become compost.
Another reason for letting them go a little bit longer before thinning is that then you will be able to see which ones are stronger and growing better and which ones are weaker, so you can cull the weaker ones.
But did you catch where imafan said "thin to 4" apart"? That means one
plant every four inches. They don't have to be that far apart right now while they are still small, but that is the ultimate spacing you will be going for. You can get there in stages. Once they get true leaves, you can thin enough that none of them are touching and each little plant has a little bit of space around it. Then as they grow, you can keep culling weaker ones, until you get to ultimate spacing.
