Understanding liquidity

Hi all, I am trying to understand liquidity a lot more these days for the sake of being able to find undervalued coins on my own and really what I'm trying to find out is what constitutes as a good amount of liquidity.

For starters, I use ETC and BTC as benchmarks because obviously they would be the most liquid of cryptocurrencies and I've looked at the "liquidity" section of CMC and Uniswap and whatever number it is I assume its a good one. For example in the following link I see that on CMC ETH trades on multiple CEX with a ton of pairs with the highest liquidiy numbers being between 600-900 (and im not quite sure what these numbers represent yet) ETH CMC.

On uniswap pairs, I see thisfor ETH. In this case I'm assuming that the TVL is the liquidity and I see that there is nearly 1b$ in liquidity and a 24h trading volume of nearly 2b.

For this coin that I am evaluating here is what I see on CMC (for reference, the coins market cap is ~27M with a current 24h volume of 4m). I don't think this is that bad and I told myself that I am willing to wait for this coin to moon, but when revisiting the topic of liquidity I went to the uniswap pairs page and there was nothing that came up for this token on there.

Am I looking at this correctly? Is this a bad sign? Can I get a further explanation on all of this?
