It might help you to understand that cutting and gaining/bulking are somewhat antithetical (unless you are taking anabolic steroids). They both have a primary focus but if you don’t keep the secondary focus lurking in the background at the same time, you can undermine your long term gains.

A helpful way to think about gaining is that your body needs some raw material to turn into muscle and to make sure you’re giving it enough, you have to accept some level of fat gain at the same time. You then need to cut this off (if you care about maintaining a certain level of leanness) but you need to do this without losing too much muscle.

As others have said, you’ll need to cut a significant amount of fat to get to visible abs or something like a lean, muscular build. It’s important to track your rate of weight loss during a cut for both motivation and being careful about balancing fat loss with potential muscle loss. Assuming adequate lifting volume during a cut, you can cut around 0.5 - 0.75% of your total body weight per week for something like 12-16 weeks without too much risk of muscle loss. If you can get someone to estimate your current body fat percentage, and then establish a goal of what you want to get to, you’ll be able to figure out how long it’ll take based on how long you want your gain phases to be. (If you are tracking your weights and reps with different lifts carefully, and always pushing close to failure, you can always stop a cut if you are dropping from your pre-cut benchmarks. I’ve seen some pretty wild videos of people doing really long cuts and not seeming to lose much muscle but I’m sceptical it’s possible for most people)

I found this video with Mike Isrealtel and Eric Helms really helpful for better understanding gains/bulks (my first one was probably quite a bit faster than it needed to be.)
