CK provides you with a VantageScore, not a FICO score. Since any place you apply with will be looking at your FICO score, not a VantageScore, you should ignore your CK score(s) and obtain a FICO score ASAP. The quickest way for you to do that for free is to go to creditscorecard.com and within a minute you'll have your Experian FICO 08 score. This score will update once monthly if you remember to log back in.
Experian is only 1 of 3 reporting agencies that potential creditors will access your report from. Prior to apping for credit cards it would be smart to see a FICO score from all 3 bureaus IMO. To do this, it costs you $1.00 at Credit Check Total. For a $1 trial membership, you'll get your EX, TU and EQ FICO 08 scores. The EX score you get from CCT will exactly match the EX score you got for free from creditscorecard. Your 3 scores will normally only fluctuate maybe 20 points between top and bottom score (sometimes 30-35 in rare instances) assuming bureau information is identical. If one of your scores is significantly higher or lower than the other two, it means that there's a major difference between the reports such as a negative item being present on one or two but not on the other one or two. These are things you need to know before apping for credit cards. For example, say your 3 FICO 08 scores are EX 620, TU 638 and EQ 689. It could mean that your EX and TU reports have a negative item present that isn't present on EQ. What does this mean for apping? Well, if you were considering an Amex card, they always pull EX, so with a 620 score it wouldn't be a good idea. If you were considering a Discover card, they often pull EQ, your best score, so that wouldn't be a bad idea. These are just examples, of course.
The bottom line is that unless you know where you stand currently with respect to your FICO scores, it's very difficult to make any suggestions at all as to whether or not you should app, which cards you could potentially be approved for, etc.
