will i be able to improve just by playing at home and watching videos?
This is a tricky question. If you play a lot you will improve at your way of playing. That's what almost all recreational players do. After a few years we reach a level where the way we play can't take us any further. The average for this seems to be around usatt 1500, but some people get to 1800 and others are stuck around 1200, whatever. If they want to improve further they would have to sort of start over and unlearn some habits that are blocking their progress. Usually this is around footwork, but also serves, ball contact, every technique, plus tactics. Changing habits is much, much, much harder than making them in the first place. So most people would require a coach, lots of time, and a pile of money to do it. And they don't. So you can go into any club and see people who have been playing the same way at the same level for five or ten years or longer. It's still fun to play, good exercise, see your friends and all that. Nothing wrong with it at all.
So about playing at home and watching videos. It could work, but some extra effort would be needed from you. Here's a couple points in no particular order.
You need to separate "training" from "playing". And you need to know which one you are doing at all times. They are two different activities.
Training means doing a drill, a multiball feed, practicing serves, shadow strokes and footwork. Working on one thing over and over and over in a controlled situation.
When you are training you must be working on something specific. Like you know what it is. I am working on serving low, short backspin could be one. Or I am working on my backhand block vs loops. Or I am working on my footwork moving to my left after a push comes long to my wide forehand, I loop, and then the next ball is blocked to my backhand. There are a nearly infinite number of things you could be training. But the basic ones are grip, stance, side-to-side movement, basic straight backspin and no-spin serve, push, hit, block, loop, forward and back movement, receive, smash, lob, and chop. When you have a few of those techniques then you can start assembling them into realistic game scenarios. Training becomes considerably more entertaining at this point.
You don't have a coach at home, you have to be your own coach. So if you watch a video, you have an idea of what it is you want to copy, then you must video yourself doing that, watch yourself, compare it to the model video. The more frequently you can do this, even during training, the better it will work. There are some apps for recording yourself and playing it back right away.
Part of being your own coach is also to have an idea of where you are now as a player, where you are trying to get to (like the play style you asked about in the OP) and what the steps are to get there. Make the steps small. So don't start with Ma Long's forehand. Seriously the two biggest problems that limit amateur players are grip and stance. Followed very closely by movement/footwork. If you only hit on forehand and backhand until you have those three things set then you will have a good foundation to add more skills.
After training, then you play. It's always good to play after every training. And don't think too much about what you worked on, then you are like half-training and not keeping the activities separate. Just play. If you want to coach yourself from your play, record it and watch it later, when you are being the coach. But during games try to remember, players play, coaches coach.
